Features

uSpecial used to real-time detect CO₂ level in air ducts.

uNDIR infrared CO₂ sensor inside with Self-Calibration and up to 15 years lifetime

uHigh accuracy humidity and temperature detection&display optional

uWith LCD or without LCD selectable

uProviding one dry contact output with presetting the setpoint

uModbus RS485 communication interface optional

uWireless of ZigBee protocol optional

uSmart structure with easier wire connection through the external pipe

uProvide four types: wall mounted, duct mounted, split and plug & play

uFor plug & play type, special design a photosensor inside to detect

day/night and change the working mode of the CO2 generator

uFor duct probe type, special the 180° rotatable fastness position of the

probe can be used in two directions of air flow.

uReplaceable filter in the probe and extendable probe length

uDesign the convenient and easier buttons for operation
