5 ANEMOMETER Displays air velocity in feet per minute (meters per second indication available) Accuracy better than ±2% of reading Rugged construction Rigid vane spokes retain calibration Compact and easy to operate - simply hold instrument directly in airstream and time its operation over a one minute interval Retains velocity reading when removed from airstream Meets O.S.H.A. ventilation requirements Calibration traceable to N.I.S.T. Designed to provide fast, accurate air velocity readings over a wide range. Low friction ball bearing design responds to minimal fluctuations in air flow. Remote swing vane probe for measurements in hard-to-reach locations. Data Hold allows user to freeze the displayed value. Ideal when reaching into an air duct. Durable housing case is made of lightweight ABS plastic. The Turbo Meter is based on the principle that a freely turning turbine will rotate at a speed directly proportional to the wind speed. To insure maximum sensitivity and accuracy, the turbine is suspended on sapphire jewel bearings, and its rotation is sensed by an infrared light beam which adds no friction. The resulting signal is processed electronically by a large scale integrated circuit for improved reliability and reduced size. A special three digit display is used for extra resolution and provides excellent viewing contrast in bright sunlight. A handy switch selects between four different scales for unmatched versatility. The totally enclosed turbine and compact size make it easy to carry, so you always have it with you when you need it.

6 ROTATING VANE ANEMOMETERS The LCA30VT is an electronic rotating vane anemometer providing a direct reading of air velocity. It has a single push button control in the hand grip. When this button is pressed and held down, the instrument averages the air velocity over three or six seconds. The air velocity is displayed digitally, and the reading is held as long as the button remains depressed. The LCA30VA operates on the same basis but can also provide direct reading of volume flow with the facility to directly input duct or grille area. The LCA30is offers the same features as the LCA30VA but is certified by BASEEFA to be intrinsically safe to EEx ia IIC T5 Zone 0 hazardous areas. All units are completely self-contained battery powered units requiring no separate timer, and can be used with one hand. They are robust and reliable, and no mechanical link between the vane and the readout; the vane itself is the only moving part. The casing is molded from a high impact ABS material.

16 THERMO-ANEMOMETER The microprocessor-based VELOCICALCs have advanced features to make your measurements faster, easier, and more accurate. The variable time constant feature smoothens the display when measuring fluctuating flows. VELOCICALC's sampling function integrates the measurement over the time constant, displaying a time averaged value. These features eliminate bouncing displays and take the guesswork out of taking readings. When taking multiple samples, VELOCI- CALC can display average, maximum and minimum values, and the number of readings. Another feature is the ability to simply and quickly calculate volumetric flow rate when the user inputs the duct shape and size. VELOCICALCs have a rugged, telescoping probe with etched length marks to make duct traverse measurements easier. For measurements in ceiling outlet flows or clean benches, the Model 8346-E-GB has the added feature of an articulating probe. A portable printer is available to provide hard copy documentation of your readings. Model 8925V Portable Printer comes complete with built-in rechargeable battery pack, 115 VAC adapter/ charger, cable, belt clip and 5 rolls of paper.

19 The only portable, non-electrical instrument for use on virtually every air velocity application Measure air velocity and static pressure (7 ranges) Professional accuracy Exclusive range selectors Interchangeable probes Completely mechanical Safe for hazardous environments Completely Portable Kit includes: 6000AP Meter, 6030CP & 6030DP Range selectors, 6050P Lo-flow probe, 6060P-12 Pitot probe, 6070P Diffuser probe, 6080AP & 6080CP Static pressure probes, 2161 Hose (2), 1010A Carrying Case VELOMETER KIT NIST traceability For work with legal implications or subject to challenge, all velometers are provided with a Certificate of Calibration traceable to NIST. The Standard of Professionals The Series 6000 Velometer Kit provides quick, accurate air velocity measurements from as low as 50 fpm to as high as 10,000 fpm. It is the standard of professionals in a variety of applications such as: HVAC balancing, OSHA compliance checks, energy audits, drying systems, hood and spray booth monitoring, fan and blower characteristics, and static pressure measurements. The Velometer is a swinging-vane type anemometer. Air passes through a tunnel and causes a vane and pointer to move in proportion to the air velocity. There are no batteries or electrical mechanisms to run down. It is intrinsically safe and can be used in hazardous or explosive atmospheres. The Velometer is easy to handle when making measurements, especially in awkward or hard-to-reach areas. It measures 6 x 6-1/4 x 2-3/4 and weighs only 10 ounces. The meter can be held in virtually any position and still give accurate readings. Its tough polycarbonate case features a retractable handle and raised edges for easy gripping. Broad Range Velometer The Velometer has a taut band suspension and counter balanced pointer to provide a rugged yet highly sensitive movement. The meter has seven scales, five velocity ranges calibrated in fpm (0-300, 0-1,250, 0-2,500, 0-5,000, 0-10,000) and two incheswater static pressure ranges (0-1.0, ). Accuracy is ±2% of full fpm scales and 5% on the static pressure scales. The length of the top scale is 5" for easy readability. Equivalent metric scales are also available. Exclusive Range Selectors Range changes are easy to make with the range selectors. The range selectors hold the probes and house two sets of calibrated restricters which control the ranges and eliminate the need for separate jets for each range. Each selector is capable of being shifted down from one range to the other without changing probes or connections. The two selectors have the following ranges: 0-1,250, 0-2,500, and 0-1.0" of water (Model 6030CP) and 0-5,000, 0-10,000 fpm, and " of water (Model 6030DP). Interchangeable Probes The Lo-Flow Probe (Model 6050P) is designed to be used without the range selector and is calibrated to measure air velocities in the range of 50 to 300 fpm. The 12" Pitot Probe (Model 6060P-12) is ideal for measuring air velocities at supply openings and ducts, or wherever air is being moved in a system. The 7" Diffuser Probe (Model 6070P) is for checking the volume of air flowing from ceiling and wall diffusers, and grilles (both supply and return). With the grille or diffuser manufacturers' K factor, air velocity readings can be converted directly to CFM. Two Static Pressure Probes offer different ranges (0-1.0" of water for Model 6080CP, " of water for Model 6080AP) and are ideal for verifying fan/exhaust static pressures and for establishing slight differentials in air separation systems. Velocity Ranges: 0-300, 1250, 2500, 5000, 10,000 fpm (0-1.5, 6.25, 12.5, 25, 50 m/s) ±2% f.s., all ranges Static Pressure Ranges: 0-1.0, 10.0 in. water (0-25, 250 mm) ±5% f.s., all ranges 6000AP All Purpose Velometer Kit $ P Pitot Probe $ P Pitot Probe $ P Diffuser Probe $ M332E 283

20 The Dwyer Rugged steel NEMA 13 housing Series 640 with 12 stainless steel probe on 6 connecting cable. Liquid tight Air Velocity cable entrances. Transmitter is ideal for a wide range of HVAC measurement and control applications, particularly in complete building control and energy management systems. Designed for use in reasonably clean and dry air streams, applications include multipoint air velocity measurements, supply and exhaust fan tracking, industrial hygiene and clean-room systems, air pollution studies and manufacturing or process control systems. The Series 640 brings ±2% accuracy (including linearity, hysteresis and repeatability) to these types of demanding applications at a surprising low cost. With four field selectable ranges of 0-200, , and 0-12,000 fpm, this single transmitter can be supplied off-the-shelf for a variety of air velocity measurement applications. The Series 640 Transmitter is easily installed with the mounting hardware supplied, including a split flange for securing the sensing probe in the duct. Requiring only volts AC or DC for power and having a two-wire, 4-20 ma output, electrical connections are made quickly and easily by means of a four-wire cable to plug-in terminal block through a liquid tight cable gland. The NEMA 13 housing is suitable for all indoor industrial, institutional or commercial installations. An optional probe extension is available for larger duct sizes. The central components of the Series 640 Transmitter are the velocity and temperature sensors located in the tip of the probe. The velocity sensor is a constant temperature thermistor which measures the air velocity, referenced to standard conditions, by sensing the cooling effect of the moving air passing over the heated sensor. The power required to maintain the velocity sensor temperature, as provided by the control circuitry in the electronics package, is a function of the air velocity. The velocity sensor is rugged enough to tolerate particulate contamination and still provide fast response to changes in air velocity. A temperature sensor in the probe tip compensates for a wide range of air stream temperature variations. Each transmitter is individually calibrated at our factory in a computer controlled wind tunnel. During this calibration procedure, the inherent non-linearity of the thermistor velocity sensor is automatically corrected by the appropriate programming of an EPROM in a linearizer circuit of the electronics package. 640 Air Velocity Transmitter $ A-398 Probe Extension Adapter $ AIR VELOCITY TRANSMITTER M2021E No. A-398 Probe Extension Adapter.

29 AIR BALANCERS The Flowhood unit captures the airflow from an outlet or inlet and directs it across the highly sensitive flow sensing manifold within the Flowhood base. The sensed total pressures are averaged to a single velocity pressure which is transmitted to the meter for conversion to direct airflow readout. The Flow-hood is a much faster and more accurate alternative to time consuming multiple velocity readings across air diffusers. This instrument completely eliminates the use of A k factors, and the calculations required to convert the average velocity into air flow.

33 Continuously measures fume hood airflow Combines three coloured LED s with audible alarm Low cost, reliable and simple to install AIR VELOCITY MONITOR Dwyer Model 660 Air Velocity Monitor is a practical, affordable way to alert personnel to insufficient exhaust rates in typical laboratory fume hoods. No remote sensors or complicated wiring - just a single device with an integral flow sensor powered by 24 VAC. A sensitive constant temperature thermistor bead is centered in the flow tube which is connected to the fume hood side wall via 1 1/2 flexible tubing. The fume hood blower simultaneously draws air at a proportional rate through both the open sash area and the Model 660 Air Velocity Monitor. By accurately measuring this sampling, the instrument provides continuous assurance that proper ventilation is being supplied - and warns when its not! As the cooling effect of moving air changes the thermistor output, electronic circuitry varies the current level to keep temperature at a factory set standard condition. By comparing the amount of current needed to maintain this standard temperature versus normal current, velocity is accurately calculated and indicated by the red (low), green (normal), and yellow (high) LEDs. An audible alarm is also initiated upon a low flow condition in case the visual warning light is overlooked. Manual acknowledgement is required to silence. A momentary contact Test pad allows confirmation that all warnings are operating properly. Because of the wide range of sizes, configurations and flow requirements of various types of fume hoods, the Model 660 Air Velocity Monitor includes field adjustable settings for both low and high limits. A suitable flow measuring device such as a Dwyer Model 480 Vaneometer or Model Handheld Thermal Anemometer is used to indicate the flow rate while adjusting the sash door or blower speed for specified limits. As low and high flow levels are reached, individual potentiometers are set to activate the red and yellow LEDs, respectively. The green or Normal LED will operate automatically when flow is between the Low (0-150 fpm) and High (0-275 fpm) setpoints. Once calibration and installation are complete, settings are inaccessible from the front panel to discourage tampering. Mounting holes are spaced to fit standard single gang electrical box or unit can be flush mounted on fascia of fume hood side wall in a x (54 x 74.5 mm) opening. Mounting template included on instructions.

40 Differential Pressure Static Pressure Velocity Variable Time Constant Calculates Average Printer Output NIST Calibration Certificate DP-Calc Micromanometers allow you to easily make the HVAC differential pressure measurements you need. Differential pressure readings include static pressure, total or velocity pressure, as well as the difference from one area to another. The DP-Calc can be sued to measure pressure and velocity in ductwork, pressure drops across filters or coils to determine performance, differential from room to room as in clean rooms or abatement areas and differential from the building to the outside for indications of indoor air quality problems. The DP-Calc can be used by anyone, test and balance professionals, HVAC contractors, facility engineers, maintenance workers, building owners and managers, inspectors and consultants. The Model 8702 DP-Calc measures the differential pressure, calculates velocity, and averages up to 255 data points. The data can then be printed to a portable printer to produce a hard copy of your readings. Easy to use, this model is a cost effective alternative for your differential pressure measurement needs.

50 STATIC PRESSURE SENSORS A-301 A-302 A-303 Used to sense static pressure drop across air filters, coils, fan discharge pressures, etc. To sense static pressure, we offer tips with a variety of fittings and accessories. They are used with manometers, Magnehelic gauges, pressure switches and other controllers to show (or control from) static pressure drop across air filters and coiling coils, blower inlet and discharge pressures. The four angles tips shown have 4" insertion depth. Each has four radially drilled 0.4" sensing holes. All except Model A-305 mount in 3/8" hole in duct. For portable use, a magnet holds Model A-303 in place. Model A-305 is used where a very low actuation or sensing point is required on a pressure switch or gauge or where response time is critical. Model A-307 and A-308 are suitable for use in low velocity systems or where the need for accuracy is less critical.

53 SMOKE PUFFER One of the most convenient and widely used smoke sources. Provides smoke on demand. Simply squeeze the rubber bulb handle for discrete puffs or a continuous stream. Each reload smoke tube produces 250 to 500 puffs of smoke. After use, unused smoke left in tube is preserved by capping with a breech plug. Sealed glass smoke tubes can be stored indefinitely. Supplied in a convenient carrying case Smoke Puffer w/ 10 Smoke Tubes $ Spare Smoke Tubes, pkg. of 10 $ Spare Rubber Puffer Bulb $51.00 SMOKE CANDLES Studying Air Flow Smoke mixed with air or gases simplifies the observation of flow patterns in all types of apparatus or wind tunnels, indoor and outdoor areas, to mention a few applications. Heating and air conditioning units can be properly balanced by observing the discharge from grilles or registers and adjusting until satisfactory. Smoke candles are recommended for checking relatively small air capacity units such as exhaust fans. Detecting Leaks Highly visible smoke readily blends with air and gases, simplifying the observation of airflow patterns or quickly pinpointing leaks. It does not support combustion or leave a visible residue. Leaks visible without smoke can instantly be seen after smoke is added. The odor of escaping smoke also assists in pinpointing leaks. The tedious and time consuming soaping of piping systems and duct work for leaks can be eliminated by inducing sufficient smoke to fill an area approximately twice as large as the area being tested. Model 1A - Smoke Candle Burns for approximately thirty seconds and generates 4000 cubic feet of smoke. Size: 1-1/2" x 1-1/2". Model 2B - Smoke Candle Burns for one minute generating 8000 cubic feet of smoke. Size: 1-1/2" x 6" Model 3C - Smoke Bomb Generates a big 40,000 cubic feet of smoke while burning for two to three minutes. Size: 1-1/2" x 6" Model WC3 - Smoke Bomb Generates 40,000 cubic feet of smoke over a period of 3 minutes. Double-wicked, furnished with clips for attaching multiple units thereby extending smoke-generating time.
