Infrared carbon dioxide (CO2) sensor Edinburgh Instruments
GasCheck

The GasCheck infrared gas sensor is a series of low CO2 sensors which features high accuracy, good long term stability, negligible cross sensitivity, small size and low power requirement.

The basic GasCheck is available in three ranges 3000 ppm, 3% and 10% with a 0 to 1 V non-linear output. A linearisation board can be added as an option to give linear 4 to 20 mA output.

The option of a diffusion assembly is available for the 3000 ppm unit.

Originally developed for measuring CO2 concentrations in laboratory incubators, the GasCheck range has now also been adopted for a wide range of applications where accurate measurement of CO2 is required, but with the benefits of low cost and compact design.
