Soil Carbon Flux Analyzer – Portable Automatic Measurement System: PS-9000 | LICA UNITED TECHNOLOGY LTD
PS-9000 is a portable automatic soil carbon flux analyzer for field measurements and soil respiration research.
The PS-9000 Portable Soil Carbon Flux System is an advanced field instrument designed to accurately measure CO₂ flux between soil and atmosphere using the dynamic chamber method. It integrates control, measurement, data storage, and processing into a single unit, enabling researchers to perform real-time, in-field monitoring of CO₂ concentration changes. By including sensors for air temperature, barometric pressure, and soil temperature, the PS-9000 ensures precise, consistent, and reproducible data for agronomic, environmental, and climate studies.
