CO₂ Probe GMP252
CO₂ Probe GMP252
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 operating temperature range is -40 … +60 °C and the measurement range is 0 … 10 000 ppmCO2, and even up to 30 000 ppmCO2 with a slightly reduced accuracy.
The GMP252 probe can also be connected to the Indigo 200 Series host devices to extend its features, for example, for a display or relays.
The GMP252 replaces the following discontinued products: GMM222, GMP222 and GMT222.
The Vaisala CARBOCAP® Carbon Dioxide Probe 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. It has full temperature and pressure compensations of CO2 measurement – integrated temperature measurement for compensation purposes. The sensor head is heated to prevent condensation. A calibration certificate is always included with the product.
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 short introduction video about Indigo or read more about it on the Indigo 200 Series product page.
The warranty for the GMP252 is 24 months.
*)All GMP252 probes manufactured from 2017 onwards with serial numbers starting with the letter N or latter in alphabetical order have full Indigo compatibility.
