CO2 Transmitter
CO2, Temperature & Humidity Transmitter
and CO2 Controller with Relay output
(AVC-310 Series)
Made in Taiwan
AVC-310 series CO2 transmitter is designed for measuring the ambient carbon dioxide concentration or with optional measurement of temperature & humidity and provide signal output for monitoring or control. Utilizing NDIR sensing element ensures its accuracy of measurement. By controlling the ventilation or air-conditioning system based on actual demand, it helps to reduce energy consumption while maintaining a healthy indoor climate.
