British GSS probe-type infrared carbon dioxide sensor (CO2 sensor)
The C20 probe-type infrared carbon dioxide sensor uses narrowband NDIR infrared technology, employing an LED and a matching photodiode, operating in the 4.26μm narrowband region. The LED itself is a stable, long-life light source and does not require the filtering process needed by traditional tungsten filament light sources. These solid-state optical components are equipped with a reference photodiode, ensuring the sensor's long-term stability and accuracy.
