1 ph nalyzer (4-wire system transmitter) ORP nalyzer (4-wire system transmitter) HM-6 HM-6 The HM-6/HM-6 is a field installation type ph/orp analyzer (transmitter) that is housed in a robust, die-cast aluminum enclosure. The unit runs on a universal power supply with automatic voltage regulation (9~64V), is equipped with a digital display screen, and provides a number of practical functions. Features The unit features a dual transmission output (4~mD) for ph (ORP) and solution temperature. The output range for the ph (ORP) and solution temperature can be set to a value within the prescribed range. Note that the output circuits share a common negative terminal. The unit is equipped with an internal memory, which can store the data for up to different ph standard solutions. The unit also features an electrode with a built-in temperature sensor that eliminates the hassle of inputting information such as the solution values and temperature during calibration. In addition, the stability judgment function allows for accurate, operator-error free calibrations using standard solutions. (HM-6) The transmitter judges the quality of electrode characteristics based on calibrations performed with standard solutions (HM-6) or ORP check solutions (HM-6). quipped with a function for detecting cracks in glass electrodes. (HM-6) In addition to compensating the temperature of the electromotive force applied to the glass electrode, the transmitter can also convert (compensate) the reference temperature for the ph value of a sample solution. When converting the reference temperature, the ph temperature coefficient of the sample can be HM-6 specified. Thanks to these features, the transmitter can also be used for the measurement control of boiler water and other similar liquids. There is also a function for manual temperature compensation. This function makes it possible to compensate the temperature for electrodes with a temperature compensation resistance that falls outside the specifications (kω at, or kω at ), as well as for electrodes that are not equipped with a temperature compensation resistor. (HM-6) In maintenance mode (ST-Y), the transmission output can be held at the value immediately before switching modes. The alarm contact output is disabled in this mode, ensuring that there are no disruptions to the control system.* The unit can also be configured to automatically switch back to measurement mode after a specified amount of time has passed. This feature is especially convenient for when you forget to disable maintenance mode. In addition, when combined with a cleaner equipped with a built-in timer, the transmitter receives command signals from the cleaner.
