GMP251 Carbon Dioxide Probe for %-Level Measurements

The Vaisala CARBOCAP® Carbon Dioxide Probe GMP251 is an intelligent, stand-alone 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 warranty for the GMP251 is 24 months.
