CO₂ Probe GMP252

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.

The GMP252 probe is part of the Indigo product family and can also be connected to the Indigo 200 Series Transmitters to extend its features, for example, for a display or relays. The GMP252 can also be used with with the free Insight PC Software.

For spot-checking, the ideal choice is the Handheld CO₂ Meter GM70.
