Carbon monoxide gas transmitter HML

COelectrochemicalmulti-use

Carbon monoxide transmitter for detecting CO concentration in air HML and HML-N carbon monoxide transmitters are designed for measuring carbon monoxide in underground parking garages and parking halls. The measuring cell is an environmentally friendly electro-chemical cell with a long life, good long term stability, and high accuracy. As the sensor is heated, the transmitter is working also in temperatures > -30°C. The output of 0…10 V or 4…20 mA is available on the ranges of 0…100 or 0…300 ppm CO concentration for controlling ventilation. The recommended transmitter calibration interval is one year. HMV exchange kit can be used to ensure the correct transmitter function. A new calibration report is delivered with the exchange kit.
