Duct Mounting Air Quality Sensor, Selectable Output 0/10Vdc or 4-20mA
KLQ
£280.00
Description
The self-calibrating microprocessor-controlled duct air quality sensor is used to determine the air quality on basis of a mixed gas sensor ⁄ VOC sensor.
It is used to measure the air quality for quantitative evaluation of room air pollution with contaminating gases.
The air quality sensor does not trace concentrations of individual gases, but assesses the mixed gas concentration.
Detectable gases: mixed gas, vapours of VOCs, cigarette smoke, automobile exhaust gases, human exhalation, combustion smoke (from wood, paper, plastics).
The sensor‘s lifetime depends on the type of burden and gas concentration.
Specification
Power Supply: 24V AC / DC (± 10%)
Power Consumption: < 1.5W / 24V DC typical
