GMP250- Series Carbon Dioxide Probe for %-Level or ppm-Level Measurements

The GMP251 is available throughout Austria from Industrie Automation Graz, IAG.

Product Description

GMP 251

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

The GMP251 probe is part of the Indigo product family and can also be connected to the Indigo500 and Indigo200 series transmitters to extend its features, for example, for a display or relays.

The GMP251 can also be used with with the free Insight PC Software.

For spot-checking, the ideal choice is the Handheld CO2 Meter GM70.

GMP252

The Vaisala CARBOCAP® Carbon Dioxide Probe GMP252 is an intelligent, stand-alone, ppm-level probe. It's intended for measuring CO2 in agriculture, refrigeration, greenhouses, demanding HVAC applications, and for plant growth chamber manufacturers. It is suitable for harsh and humid CO2 measurement environments where stable and accurate ppm-level CO2 measurements are needed. The operating temperature range is -40 … +60 °C and the measurement range is 0 … 10 000 ppm CO2, and  even up to 30 000 ppm CO with a slightly reduced accuracy. 

The GMP252 can also be placed inside the Vaisala Radiation Shield DTR250 for measuring dynamically outdoor CO2 levels.

The GMP252 probe is part of the Indigo product family and can also be connected to the Indigo500 and Indigo200 series transmitters to extend its features, for example, for a display or relays. The GMP252 can also be used with with the free Insight PC Software.

For spot-checking, the ideal choice is the Handheld CO2 Meter GM70.
