Termékleírás
The Vaisala GMP252 is an intelligent CO₂ measurement probe designed for use in agriculture, greenhouses, refrigeration systems, and demanding HVAC applications. It is ideal for harsh and humid environments where stable and accurate ppm-level CO₂ measurements are required.
With an operating temperature range of −40 to +60 °C and a measurement range of 0 to 10,000 ppm CO₂(extendable up to 30,000 ppm with reduced accuracy), the probe offers high flexibility across various applications.
For outdoor measurements, the GMP252 can be used with the Vaisala radiation shield DTR250, enabling dynamic CO₂ monitoring in ambient conditions.
As part of the Indigo product family, the probe can be connected to Indigo500 and Indigo200 transmitters to expand functionality, such as adding a display or relay outputs. It is also compatible with the Insight PC software for easy configuration, diagnostics, and calibration.
