Wholesale Electrochemical CO Sensor
CO Sensor 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
