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