CO₂ Probe GMP251

The Vaisala CARBOCAP® Carbon Dioxide Probe GMP251 is an intelligent, stand-alone, %-level probe for measuring CO2 in life science incubators, cold storages, fruit and vegetable transportation, and in all demanding applications where stable and accurate percentage-level CO2 measurements are needed. The operating temperature range is -40 … +60 °C and the measurement range is 0 … 20%CO2.

The GMP251 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.

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

The GMP251 replaces the following discontinued products: GMM221 and GMT221. Please note that spare parts and accessories for the GMP221 probe are still available and can be purchased in the Vaisala online store.
