AVC-310 Series
CO2 / Temperature & Humidity Transmitter
AVC-310 series 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. It is perfect for building climate control, greenhouse,
mushroom farms and other processes where environmental control or monitoring is required. By controlling the ventilation or air-conditioning system based on actual demand,
it helps to reduce energy consumption while maintaining a healthy indoor climate.
