Sensaphone FGD-0066 - 4-20mA Type Air Quality Sensor
The Sensaphone Indoor Air Quality Sensor allows you to monitor levels of pollution from 0-100% with any Sensaphone that accepts a 4-20mA input signal. Popular applications include schoolrooms, office buildings, and parking garages.
The Air Quality Sensor uses a tin dioxide semiconductor sensor to detect oxidizable gases and is specially designed to have high sensitivity to gaseous organic materials, which are components of indoor air pollutants. These air contaminants include cigarette smoke, cooking exhaust, automobile exhaust, solvents and many others.
Requires a 24VDC power supply FGD-0053 to operate.
