Vaisala GMP251 CARBOCAP® Carbon Dioxide Probe is an intelligent, stand-alone probe for measuring carbon dioxide (CO2) in a variety of applications. This probe was optimized for use in incubators, but is also a great solution for cold storage, fruit and vegetable transportation, food and beverage production, and in all demanding applications where stable and accurate %-level CO2 measurements are needed.

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 sensor.

GMP251 provides temperature compensation of the CO2 measurement according to the ambient temperature. Effects of pressure and background gas can also be compensated for to ensure the most accurate results.

This probe is configurable with a full-scale measurement range of 0 … 20 %CO2, but can be used at any range in between. The operating temperature range is -40 … +60 °C (-40 … +140 °F) and the probe housing is classified as IP65. Condensation can be prevented by enabling the built in sensor heating function.

A standard ISO 9001 factory calibration certificate is included in delivery. ISO 17025 accredited calibration is available upon request.

GMP251 can also be combined with the Vaisala MI70 hand-held indicator or INDIGO200 Series Transmitter if a display or relays are needed. 

GMP251 can be used as a replacement for the discontinued GMM221 or GMT221 models. Compatible with Vaisala Insight software (download for free at www.vaisala.com/insight).
