Description
The Vaisala CARBOCAP® GMP252 carbon dioxide sensor is a smart, self-contained sensor for measuring concentrations in ppm. It is suitable for measuring CO2 in agriculture, refrigeration, greenhouses, demanding HVAC applications, and by grow room manufacturers. It is ideal for challenging and humid CO2 measurement environments where stable and accurate CO2 level measurements are required. The operating temperature range is -40 to +60 °C, and the measurement range is 0 to 10,000 ppm CO2, with a lower accuracy of up to 30,000 ppm CO2.
The GMP252 can also be placed inside the Vaisala DTR250 radiation shield for dynamically measuring CO2 levels outdoors.
Belongs to the Indigo product range
The GMP252 probe is part of the Indigo product family and can also be connected to the Indigo500, Indigo300, and Indigo200 transmitters to expand functionality, such as display or relays. The GMP252 probe can also be used with the free Insight PC software.
For spot checks, we recommend the Indigo80 handheld indicator.
The GMP252 model replaces the following discontinued products: GMM222 and GMT222. Spare parts and accessories for the GMP252 probe are still available.
