The Vaisala CARBOCAP® Carbon Dioxide Probe GMP251 is an intelligent, stand-alone, %-level probe for measuring carbon dioxide 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 200 Series host devices to extend its features, for example, for a display or relays. Watch this introduction video about Indigo or read more about it on the
Indigo 200 Series product page.
The warranty for the GMP251 is 24 months.
