Vaisala CO2 Probe GMP251 GMP252 Carbon Dioxide Probe
Important note : the price on the website is not correct , pls contact us for the price and delivery time , thanks for your understanding.
The Vaisala CARBOCAP® Carbon Dioxide Probe GMP251 is an intelligent, stand-alone, %-level probe for measuring CO2 in life science incubators, cold storage facilities, fruit and vegetable transportation, and in all demanding applications where stable and accurate percentage-level CO2 measurements are needed. The operating temperature range is -40 … +60 °C and the measurement range is 0 … 20%CO2.
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. It has full temperature and pressure compensations of CO2 measurement – integrated temperature measurement for compensation purposes. The sensor head is heated to prevent condensation. Digital output over RS-485: Modbus & Vaisala Industrial Protocol. A calibration certificate is always included with the product.
