【Product Overview】

This product was developed to detect the presence of CO2 in the ambient air and help people to take care of the Indoor Air Quality.
The compact device is designed for use in HAVC in the building. The demand controlled ventilation in the building, also the
greenhouse with the CO2 concentration control.
By using the CO2 monitor as the indicator, it can easily get the current CO2 concentration together with the ventilation rate. And then
adjust the ventilation to the comfort condition automatically by the setting data. So the over-ventilation of the building can be reduced,
and the energy can be saved. The ZGw08VRC can be widely used in the office building, green house, school, exhibition, shopping
mall.
The ZGw08VRC is easy to use and has many features:
NDIR ( Non-Dispersive-Infrared) technology used to measure CO2 concentration

Three different LED display show the current Indoor Air Quality situation.

Voltage (0~5V), Current loop and relay output.

 Reliable Sensor provides long-term calibration stability.
The visual and audible alarm function can be adjustable by user.
