SRS2000T Soil Respiration System

The SRS2000T is a versatile, portable soil respiration system designed to accurately and reliably measure soil CO2 and H2O gas exchange under controlled or ambient environmental conditions.

Compact, rugged, and field-ready, this advanced device automatically calculates soil respiration parameters and enables precise control of the soil chamber climate. With an intuitive touch-screen interface, integrated GPS, and robust data storage, the SRS2000T is an indispensable tool for soil scientists and ecological researchers.

Key features

  • Portable and Rugged Design: This lightweight (4.1 kg) device is designed for use in field conditions and can continuously operate for up to 16 hours on a single battery charge. It is easy to carry and take measurements at multiple sites where soil collars are inserted.
Soil collars in field
  • Infrared Gas Analysis: Accurate CO2 (0-3000 ppm, 1 ppm resolution) and H2O (0-75 mbar, 0.1 mbar resolution) measurement using advanced laser-trimmed sensors.
  • Chamber Climate Control: Precisely regulates CO2 concentration (up to 2000 ppm) and humidity (above/below ambient).
  • Real-Time Data Visualization: Set the graph’s update frequency to every 2 to 30 seconds. The touchscreen is a colour WQVGA with 360° visibility for instant data review and graphical representation. 
  • Integrated GPS: Records latitude, longitude, and altitude with every measurement, facilitating spatial analysis.
  • Extensive Data Storage: Removable SD cards (up to 32GB) for storing thousands of measurements, easily transferable to a PC via USB.
  • Rapid Measurement Protocols: Quick setup and stabilisation, allowing efficient measurements in the field. 

Soil chamber & accessories

The SRS2000T includes a two-part soil chamber. The soil collar is inserted into the soil. The chamber head, which comes in either transparent or opaque options, is inserted onto the collar, forming a seal before taking measurements. Multiple soil collars can be inserted across a field. Additional accessories include:

  • Soil Temperature Probe: Measures soil temperature in real‑time.
  • PAR Sensor: Monitors photosynthetically active radiation (PAR) at the chamber surface.

Applications

  • Soil Carbon Flux Studies: Measure soil respiration to understand carbon cycling.
  • Climate Change Research: Assess CO2 emissions from soil in different environmental conditions.
  • Agronomy and Soil Health: Evaluate soil microbial activity and gas exchange in agricultural fields.
  • Ecosystem Monitoring: Track soil respiration rates across land-use and ecosystems
