JQAW-3 series CO2 sensor adopts American GE two-channel high quality CO2 module design and dual channel nondispersive infrared principle(NDIR), gold-plated optical element,long time working assure the stability and reliability of the CO2 measurement.with 4 mA ~ 20 mA current, and 0V~ 5V, 0V~ 10V voltage output ,it's an indoor environment measurement transducer.

Sensor, transmit integrated design, suitable for indoor environment measurement of CO2.It also can applied to a high concentration occasion in a long term.

GE dual channel CO2 module, have calibration function

Nice appearance, simple installation

Stable performance and long service life
