Description

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 CO 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 500 and 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.

The GMP252 replaces the following discontinued products: GMM222 and GMT222. Spare parts and accessories for the GMP222 probe are still available and can be purchased.
