Percentage level carbon dioxide measurement for life science incubators, cold storage facilities, and demanding applications The Vaisala Carbon Dioxide Probe GMP251 is an intelligent and independent percentage level probe used to measure CO2 in life science incubators, cold storage facilities, fruit and vegetable transportation, and demanding applications, all of which require stable and accurate measurement of percentage level CO2. The working temperature range is -40 to+60 ° C and the measurement range is 0 to 20% CO2.
The Vaisala GMP251 is based on Vaisala's second-generation technology and has stable performance. It uses an infrared (IR) light source instead of traditional incandescent bulb light sources, which extends the lifespan of GMP251. It has full temperature and pressure compensation for CO2 measurement - integrated temperature measurement for compensation purposes. Heat the sensor probe to prevent condensation. Digital output via RS-485: Modbus and Vaisala industrial protocol. All products come with calibration certificates
