  • Ordering Info

Series CES2000 sensor is an advanced and versatile multi-in-1 transmitter, optimized for demand controlled ventilation and building automation in residential, commercial and industrial applications. The data transmits to a BMS system or stand-alone controller using communication protocols.

* Versatile:
It measures 7 variables including temperature, humidity (RH), TVOC, PM2.5, CO, CO2, CH2O(formaldehyde) of air accurately in one device with modern design.

* Analogue Outputs, Digital interface, Display:
Digital interface: RS485 (additional sensed variables are available on the Modbus RTU).
Display: high solution back light LCD screen as optional.

* Easy Installation and Maintenance:
The snap-on design facilitates the replacement of the active front part within seconds while the wiring remains intact. Furthermore, it makes possible to wire the device without exposing the electronics to construction site pollution.


* Flexibility and versality: upto 7 signals combined in one device, except CH2O (formaldehyde) and CO2 at same time.

* Multiple signals output via digital interface.

* Superior protection for reverse voltage and overvoltage offers outstanding long-term stability.

* Wide range of working temperature.

* High reliability and excellent anti-interference performance.

* Easy installation and modern design.

* Optional high-resolution LCD display with back light.

* Wall or duct mounted type suitable for room or duct installation in HVAC system.

* OEM (Original Equipment Manufacturer) or ODM (Original design manufacturer) at request.



* Sensed variables:
