K33-ICB is a non-dispersive infra-red (NDIR) CO2 sensor module designed specifically for incubator application. With pigtail wire connections, the K33-ICB comes with internal and external mounting options.
The sensor module is powered with 12V DC and it converts the measurement into a linear voltage signal; 0 – 5V corresponding to 0 – 20 vol. % CO2.
The K33-ICB also comes with simple maintenance features. The BC wiring connection allows the user to perform a quick background calibration (BC) [sensor exposed to the fresh-air condition.]
