CO2 Probe GMP252

The Vaisala CARBOCAP® Carbon Dioxide Probe GMP252 is an intelligent stand-alone probe for measuring CO2 in the ppm range. Intended for CO2 measurement in agriculture, refrigeration, greenhouses, demanding HVAC applications and grow room manufacturers. Suitable for harsh and humid CO2 measurement environments where stable and accurate ppm CO2 measurements are required. The operating temperature range is -40 ... +60 °C and the measuring range is from 0 ... 10'000 ppm CO2, with reduced accuracy even up to 30'000 ppm CO2.

The GMP252 is based on Vaisala's proprietary 2nd generation CARBOCAP® technology for excellent stability. Instead of a conventional bulb, a new type of infrared (IR) light source is used to extend the life of the GMP252. The probe has full temperature and pressure compensation for CO2 measurement - a temperature measurement is built in for compensation purposes. The sensor head is heated to prevent condensation. Digital output via RS-485: Modbus & Vaisala Industrial Protocol. The products are always delivered with a calibration certificate.

The GMP252 is part of the Indigo family and can be used as a stand-alone probe or in conjunction with the Indigo200, Indigo300, and Indigo500 series transmitters, as well as the Indigo80 handheld indicator. Vaisala Insight PC software can be used for data visualization, easy probe configuration and field calibration.
