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 storage facilities, 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 to +60 °C and the measurement range is 0 to 20%CO_2.

The GMP251 has full temperature and pressure compensations of CO₂ measurement – integrated temperature measurement for compensation purposes. The sensor head is heated to prevent condensation. Digital output over RS-485: Modbus & Vaisala Industrial Protocol. A calibration certificate is always included with the product

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.

The GMP251 can also be used with the free Insight PC Software.
