CO₂ probe GMP251

User 's Manual Selection table

The CO2 Probe GMP251 is an intelligent, independent, percentage-level probe designed to measure CO2 in life science tanks, cold storage facilities, fruit and vegetable transportation, and demanding applications where stable and accurate percentage level CO2 measurements are required.Operating temperature range is -40 to +60 °C and measuring range is 0 to 20% CO2. The GMP251 is based on Visala's second generation CARBOCAP® technology and offers stable performance. It uses an infrared (IR) light source instead of the traditional incandescent bulb light source, which extends the service life of the GMP251.It has full temperature and pressure compensation for CO2 measurements - integrated temperature measurements for compensation purposes. Heat the sensor probe to prevent condensation. Digital output via RS-485: Modbus with Vaisala Industries Protocol.
