Air Quality Transmitter/Controller (ILH)

Application: The ILH transmitters are engineered for detecting and controlling Volatile Organic Compound (VOC) levels, temperature, and humidity in dry room spaces. By employing MEMS sensing technology, these transmitters ensure accurate and durable VOC measurement, which is closely related to CO2 levels. The information gathered by the VOC sensor enables effective demand-based ventilation control, optimizing indoor air quality.

Features:

  • VOC Sensing: The VOC sensor detects a wide variety of hydrocarbons, including cigarette smoke, exhaled breath, solvent vapors, building material emissions, and cleaning agent vapors, providing comprehensive air quality assessment.
  • Display: The N model features a display where measurement values scroll, allowing users to lock desired values for continuous viewing.
  • Control Output: The transmitter offers flexible control output options, enabling adjustment based on individual measurement values or the maximum selection of all values. Controller settings can be modified using the ML-SER tool for enhanced customization.
  • Optional Features: Various optional features are available, including VOC level indicator lights (HD-AL3), passive potentiometer (HD-P), active 0-10 V potentiometer (HD-PU), and relay (HD-R) for switching based on measurement values. Indicator light limits and relay switching points are adjustable via the ML-SER tool.
