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.
