RLQ Room air quality sensor

Room air quality sensor

Power supply 24 V AC/DC, output 0..10 V or 4..20 mA ~ 100..0% air quality referred to calibration gas, VOC sensor, IP30

Datasheet

The RLQ sensor is used to determine air quality, based on a mixed gas sensor (VOC).

  • Quantitative assesment of air pollution in rooms with contaminating gases (cigarette smoke, body odour, exhalled breathing air, emission from detergents and building materials).
  • For demand-based ventilation controls in those rooms.

Room air quality is to be understood as subjective air quality felt by human beings with their olfactory organs. As perception varies from person to person, no general definition of air quality is available. The air quality sensor does not trace concentration of any individual gas; it assesses the mixed gas and thus it is not possible to specify gas concentrations in the ppm units. A broadband VOC (volatile organic compounds) sensor is used to provide as universal value as possible. 

Detectable gases: Mixed gas, vapours of alkanoles, automobile exhaust gases, exhaled breathing air, combustion smoke (from wood, paper, plastics). The sensor can be reset by means of zero point and final value potentiometers.
