Product Details
Dual-channel Infrared CO₂ Sensor KGD - CM - 104
Product Introduction
The dual-channel infrared CO₂ sensor KGD - CM - 104 is a
dual-channel NDIR sensor. The development of the dual-channel
technology is based on the unique absorption characteristics of CO₂
gas. The signal of the measurement channel changes with the change
of the CO₂ concentration, while the signal of the reference channel
is only affected by the sensor drift. The reference channel
provides real-time correction to the measurement channel, ensuring
the measurement stability of the sensor during long-term use.
Product Features
- NDIR core technology.
- High detection range, can be customized up to 12000ppm.
- Dual-channel design, with higher precision and better stability.
- High precision.
- Matrix correction within the full range of temperature.
- Short preheating time.
