PS-9000 Portable Soil Carbon Flux Automatic Measurement System



PS-9000 Portable Soil Carbon Flux Automatic Measurement System


PS-9000 is a portable measurement system for measuring soil CO2 flux by dynamic chamber method. PS-9000 integrates the functions of control measurement, storage and data processing. It can measure the change of CO2 concentration in the chamber. At the same time, it can calculate and process the CO2 flux in combination with the data of its own measured air temperature, atmospheric pressure, soil temperature and other sensors.

PS-9000 can realize wireless operation through handheld controller, display various values measured by the instrument in real time, and modify various setting parameters.

Main features:


u  Flux measurements are accurate and verifiable;

u  Simple operation interface, one click to obtain results;

u  Light weight and easy to carry;

u  Low power requirements, convenient for outdoor measurement all day;

u  Without data post-processing, the measurement results are directly displayed and stored.
