HOLTOP HDK-CK-CO2 Carbon Dioxide Sensor 5 m for CFA/XHBQ-DMTHC H-KF2306-X1-180

The HOLTOP HDK-CK-CO2 is a carbon dioxide sensor designed as an accessory for the HOLTOP CFA and XHBQ central heat recovery ventilation systems. It monitors the CO₂ concentration of the room air, giving you information about indoor air quality. The grey unit weighs 150 g.

The sensor uses NDIR infrared measurement technology and covers a measuring range of 400 to 2000 ppm. If the system controller supports it, this can help enable demand-controlled ventilation. The 5-metre connection cable allows more flexible placement.

The sensor is useful in apartments, family houses, offices and shared spaces where adequate air exchange matters. Compatibility with the HOLTOP CFA and XHBQ units depends on the controls and connection options available.
