Introduction:
CO2 transmitter
with 6 indicators to indicate the CO2 level
one relay output is optional to control a ventilation device
Features
1) Design for HVAC, ventilation systems, offices, classrooms orother application places.
2) Real-time detecting CO2 level. Temperature and humiditydetection is optional.
3) NDIR infrared CO2 module inside with four CO2 detection rangeselectable.
4) CO2 sensor has Self-Calibration Algorithm and 15 yearslifetime
5) Mounted type and duct type selectable
6) Special 6 lights Indicates CO2 level and makes it clearshow.
7) Special model with a touch button as a controller to operatea fan control.
8) Providing up to three analog outputs forCO2/temperature/humidity.
9) One relay output is available
10) RS-485 communication interface is optional: 15KV antistaticprotection, independent address setting
11) 24VAC/VDC power supply can be connected with the wireterminals, also a power adaptors plug connected into the socketavailable.
12) CE-Approval
