CO Transmitter HML

HML carbon monoxide transmitters are designed for detecting carbon monoxide in underground parking garages and parking halls. The CO sensor detects carbon monoxide with an electrochemical cell. The electrochemical cell has good long-term stability and high accuracy.

CO Transmitter HML

The transmitter operates correctly also in subzero temperatures down to -30 °C because the sensor is heated.

One CO concentration output (0...10 V or 4...20 mA) is available in the ranges of 0...100 or 0...300 ppm for controlling ventilation.

The recommended transmitter calibration interval is one year. You can calibrate the transmitter using the HMV calibration kit. A calibration report is delivered with the calibration kit.
