The Vaisala GMP252 Carbon Dioxide Probe is a new intelligent probe for measuring carbon dioxide. This robust, stand-alone measurement device is designed for use 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 incorporates an internal temperature sensor for compensation of the CO2 measurement according to ambient temperature. The effects of pressure and background gas can also be compensated for. The measurement range is 0 to 10,000 PPM CO2 and the sensor can be used for measurements even up to 30,000 ppm CO2 with reduced accuracy. The operating temperature range of the probe is wide and the probe housing is classified as IP65. Condensation is prevented as the internal sensor head is heated. The GMP252 is resistant to dust and most chemicals, such as, H2O2 and alcohol-based cleaning agents.

The GMP252 is a compact probe that is easy and fast to install in a number of ways. It's easy to plug in and plug out. The surface of the probe is smooth, which makes it easy to clean. The probe provides several outputs for the CO2 measurement, analog current and voltage outputs as well as digital RS485 with Modbus protocol.
