Product Details
Single-channel Infrared CO₂ Sensor KGD - CM - 103
Product Introduction
The single-channel infrared CO₂ sensor KGD - CM - 103 is a CO₂
sensor based on the principle of non-dispersive infrared
absorption, which can monitor and display the CO₂ concentration in
real time. This sensor features high accuracy, superior
performance, a compact structure, and easy installation. It is
suitable for applications such as indoor CO₂ concentration
detection, air quality control, and energy-saving control. Examples
include fresh air systems, air conditioning control, air quality
monitors, and plant cultivation.
