Aecl
CO2 / Temperature & Humidity Transmitter
and CO2 Controller with Relay output
(AVC-310 Series)

Made in Taiwan

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 greenhouse, mushroom farms, wine cellar, brewery or 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.

Features:

  • Rapid response time, high stability, high accuracy
  • Internal sensing element design
  • Streamline shape and elegant design
  • Complete product line and multifunction for various applications
