Features

Special used to real-time detect CO₂ level in air ducts.
NDIR infrared CO₂ sensor inside with Self-Calibration and up to 15 years lifetime
High accuracy humidity and temperature detection &display optional
With LCD or without LCD selectable
Providing one dry contact output with presetting the setpoint
Modbus RS485 communication interface optional
Wireless of ZigBee protocol optional
Smart structure with easier wire connection through the external pipe
Provide four types: wall mounted, duct mounted, split and plug & play
For plug & play type, special design a photosensor inside to detect day/night and change the working mode of the CO2 generator
For duct probe type, special the 180° rotatable fastness position of the probe can be used in two directions of air flow.
Replaceable filter in the probe and extendable probe length
Design the convenient and easier buttons for operation

Typical Applications

In office and residence areas to detect CO2 level
Ventilation control
In BAS to detect the CO2 and the data transmittance
For greenhouse and plant bin
For CO2 laboratory
