CO₂ Probe GMP251
CO₂ Probe GMP251
The Vaisala CARBOCAP® Carbon Dioxide Probe GMP251 is an intelligent, stand-alone, %-level probe for measuring CO2 in life science incubators, cold storages, fruit and vegetable transportation, and in all demanding applications where stable and accurate percentage-level CO2 measurements are needed. The operating temperature range is -40 … +60 °C and the measurement range is 0 … 20%CO2.
The GMP251 replaces the following discontinued products: GMM221, GMP221 and GMT221. Please note that spare parts for the GMP221 probe are still available and can be purchased in the Vaisala online store.
The Vaisala CARBOCAP® Carbon Dioxide Probe GMP251 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 GMP251. 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 GMP251*) 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 GMP251 is 24 months.
*)All GMP251 probes manufactured from 2017 onwards with serial numbers starting with the letter N or latter in alphabetical order have full Indigo compatibility.
