JQAW-12 CO2 Transmitter
JQAW - 12 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 0 v ~ 5 v, 0 v ~ 10 v 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.
Applies to 86 terminal box installation
Beautiful appearance, lead routing from the shell's back,suit for dark line
Stable performance and long service life
GE dual channel CO2 module, have calibration function
