CO2 sensor Features

Special used to real-time detect CO₂ level in airducts.

NDIR infrared CO₂ sensor inside withSelf-Calibration and up to 15 years lifetime

High accuracy humidity and temperature detection&displayoptional

With LCD or without LCD selectable

Providing one dry contact output with presetting thesetpoint

Modbus RS485 communication interface optional

Wireless of ZigBee protocol optional

Smart structure with easier wire connection through theexternal pipe

Provide four types: wall mounted, duct mounted, splitand plug & play

For plug & play type, special design a photosensorinside to detect

day/night and change theworking mode of the CO2 generator

For duct probe type, special the 180° rotatable fastnessposition of the

probe can be used in two directionsof air flow.

Replaceable filter in the probe and extendable probe length

Design the convenient and easier buttons for operation

CE-Approval

Wall mounted with plug & play

CO2 sensor Typical Applications

In office andresidence areas to detect CO2 level

Ventilationcontrol

In BAS todetect the CO2 and the data transmittance

For greenhouseand plant bin

For CO2laboratory
