Features:
- Real time detection of carbon dioxide in air ducts
- NDIR infrared CO2 sensor inside with self-calibration and up to 15 years lifetime
- Smart sensor probe with extendable probe for easy insertion into any air duct
- Simple and smart design and installation of sensor probe with a waterproof and porous film
- Up to 3 analogue linear outputs for measurements
- Optional Modbus RS485 interface
- CE-approval
Application/s:
- Building management for office and residential areas
- Ventilation control systems
Overview:
The T99-CO2D Carbon Dioxide sensor is designed to be installed in HVAC applications. The CO2 sensing element uses non-dispersive infrared technology (NDIR) with the patented self-calibration system to guarantee long-term stability and up to 15 years lifetime. The one or three analogue outputs are selectable by jumpers, and a Modbus RS485 communication interface is also available.
