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
