CO₂ Probe GMP252

The Vaisala CARBOCAP® Carbon Dioxide Probe GMP252 is an intelligent, stand-alone, ppm-level probe for measuring CO2 in agriculture, refrigeration, greenhouses and demanding HVAC applications. 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 ppmCO2, and  even up to 30 000 ppmCO with a slightly reduced accuracy.

The GMP252 probe can also be connected to the Indigo 200 Series host devices to extend its features, for example, for a display or relays.

The GMP252 replaces the following discontinued products: GMM222, GMP222 and GMT222.
