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.

Advantages:

High-precision and repeatable measurements using NDIR (Non-Dispersive Infrared Absorption) technology.
Simple, one-click interface for fast configuration and immediate results.
Compact and lightweight design ideal for outdoor research campaigns.
Low power consumption allowing extended operation on battery power.
Instant data display and automatic storage without post-processing.
Wireless operation and data transfer via Wi-Fi, RS-232, and SDI-12 interfaces.
