<< | < | AX-GS-CD-T81 - Carbon Dioxide Sensor with Optional RH
|
| |
|
|
The AX-GS-CD-T81 Combined Humidity, Temperature and Carbon Dioxide Transmitter uses NDIR single beam Infrared technology to monitor the CO2 levels and give both a Voltage and Current output of CO2 levels and a Thermistor to monitor the Temperature and a Thermoset Polymer Based Capacitive sensor for the RH and outputs a linear signal as either 4-20 mA or 0-5/10 Vdc. The options include a LCD display displaying the ppm levelsand Bacnet output |
