Model: F2000TSM-CO2 Series

Cost-effective
CO2 detection
Analog output
Wall mounting
CE

Short Description:
This is a low-cost CO2 transmitter designed for applications in HVAC, ventilation systems, offices, schools, and other public places. NDIR CO2 sensor inside with Self-Calibration and up to 15 years lifetime. One analog output of 0~10VDC/4~20mA and six LCD lights for six CO2 ranges within six CO2 ranges make it unique. RS485 communication interface has 15KV anti-static protection, and its Modbus RTU can connect any BAS or HVAC systems.
