ModBUS sensor for CO2, Temperature and Relative Humidity

The KET-CO2-300 is an advanced and versatile 3-in-1 sensor designed for installation in air conditioned areas. It accurately measures CO2 concentration, temperature and humidity in the ambient air without the need for additional compensation.

Ready for communication via RS485 connection with ModBUS RTU protocol compatible with KET-RMB-211 ModBUS bridge/Master or an X-Monitor Gateway.
