for ppm-level measurements in agriculture, refrigeration, demanding HVAC, and for plant growth manufacturers

The Vaisala CARBOCAP® Carbon Dioxide Probe GMP252 is an intelligent, stand-alone, ppm-level probe. It's intended for measuring CO2 in agriculture, refrigeration, greenhouses, demanding HVAC applications, and for plant growth chamber manufacturers. It is suitable for harsh and humid CO2 measurement environments where stable and accurate ppm-level CO2 measurements are needed. The operating temperature range is -40 … +60 °C and the measurement range is 0 … 10 000 ppm CO2, and  even up to 30 000 ppm CO2  with a slightly reduced accuracy. 

The GMP252 can also be placed inside the Vaisala Radiation Shield DTR250 for measuring dynamically outdoor CO2 levels.
