​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 GMP252 is based on Vaisala’s unique, second-generation CARBOCAP® technology that enables exceptional stability. A new type of infrared (IR) light source is used instead of the traditional incandescent light bulb, which extends the lifetime of the GMP252.

The GMP252*) probe can be connected to the Indigo 201 host device to extend its features, for example, for a display or relays. Watch this introduction video about Indigo or read more about it on the Indigo 201 product page.

The warranty for the GMP252 is 24 months.
