ILH-M-N transmitters are designed for detecting and controlling VOC (Volatile Organic Compound) level, temperature and humidity (optional) in dry room spaces. MEMS sensing technology ensures accurate and durable VOC measurement that is directly related to the CO2 level. With the VOC level information the demand based ventilation can be controlled effectively.

The VOC sensor detects wide variety of hydrocarbons such as cigarette smoke, exhaled breathing air, solvent vapours, building material emissions and cleaning agent vapours. The transmitter can be connected to any system that supports Modbus RTU protocol by using the RS-485 connection. ML-SER tool is needed in commissioning for making the Modbus settings.
