CO2 sensorIMG-CB series (CO2 sensors for measuring room atmosphere and for building ventilation control in BEMS applications)

Products with long-term stability and high measurement accuracy that promise to improve maintainability.

Due to low drift, they do not require a significant margin for the CO2 concentration control setting, which enables maximum energy savings.
Uses a high-performance air filter with a design life of ten years and is equipped with a built-in surge protection power circuit.
