Description

Carbon Dioxide Measurement Station for Demanding Measurements

The CO₂ Measurement Station, equipped with the Vaisala GMP343 sensor and Fluxscout Power Logger, is a high-precision CO₂ monitoring system designed for scientific and environmental research. It provides accurate and stable carbon dioxide measurements for ecosystem studies, soil respiration monitoring, chamber flux measurements, and ambient CO₂ observations.

The integrated Power Logger enables autonomous operation anywhere, powered by a solar panel and battery system, and ensures reliable data collection also in remote locations. Measurement data are automatically transmitted to the cloud, where they can be visualized, analyzed, and downloaded.

Key Features

  • Accurate and stable CO₂ measurement using Vaisala CARBOCAP® infrared technology

  • Temperature, pressure, humidity, and oxygen compensation for superior accuracy

  • Available as diffusion or flow-through model for soil and chamber applications

  • Compatible with Fluxscout chamber systems, and Vaisala MI70 indicator for data display and logging

  • Recalibration option via multipoint calibration with up to 8 user-defined points
