Top CO2 Controller for ventilation,Hydroponic Garden

CO2 Controller Typical Applications

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

Wall mounted

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

Duct probe mounted
