Preface:

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.
