CO2 Engine® BLG

CO2 Engine BLG is designed to measure and store records of environmental parameters such as CO2, relative humidity and temperature. The sensor  is designed for battery powered operation with low average power consumption without compromising measurement precision and resolution.

Key benefits

-Low power consumption
-Individually calibrated
-High quality



The sensor can be used in a wide range of applications such as in food transportation, storage, incubators and other high range applications.
