CO2 Probe GMP251 for life science incubators, cold storages and all demanding applications Vaisala VietNam ANS VietNam

​​​​​​​​​Vaisala VietNam ANS VietNamVaisala VietNam ANS VietNam​​​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 %-level CO2 measurements are needed.

The 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.

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 irt on the Indigo 201 product page.

The warranty for the GMP251 is 24 months.
