Probe GMP251 A4B0C1N1 Vaisala Vietnam

 

 

Precision CO₂ Measurement for Demanding Environments

The Vaisala CARBOCAP® GMP251 is a smart, standalone carbon dioxide probe designed for reliable and accurate %CO₂ measurements in demanding applications. It is ideal for use in life science incubators, cold storage, fruit and vegetable transportation, and other environments that require precise and stable CO₂ control at percentage levels.

With a wide measurement range of 0…20% CO₂ and an operating temperature range from -40 to +60°C, the GMP251 is built to perform in harsh conditions without compromising accuracy.


Advanced Technology – Superior Stability

The GMP251 is based on Vaisala’s second-generation CARBOCAP® sensor technology, which provides exceptional long-term stability. Instead of a traditional incandescent bulb, it uses a next-generation infrared (IR) light source for extended lifespan and lower maintenance requirements.
