Accurate Soil Respiration

The SRS-1000 consists of a console programming unit and a soil respiration chamber. The highly accurate
miniaturized CO infrared gas analyzer is housed directly adjacent to the soil chamber, ensuring the fastest 2
possible response to gas exchanges from the soil. This “ open system� has an operating range of 0-2000ppm, with
a resolution of 1ppm. The IRGA has been designed to have minimal drift. All measurements are automatically
compensated for atmospheric pressure and temperature.
The SRS-2000, although slightly heavier, offers humidity control designed for wet soils and a longer battery
charge life.
Pressure variations in some soil chamber designs can lead to a suppressing or enhancing of CO exchanges. The 2
ADC Soil Respiration Chamber has been specifically designed to ensure that there is no internal pressure
gradient. Incorporation of an integral pressure release valve ensures that there is no significant difference
between the chamber head space and outside atmospheric pressure. The chamber consists of an upper chamber
and a metal collar.
The collar is inserted into the soil to ensure a good seal and optimal upper chamber positioning, regardless of
soil condition, and to ensure that total soil flux activity is measured with the chamber area. This collar maybe left
in the soil for long term comparative studies.
In addition to gas exchange data and soil flux calculations the system also measures soil temperature. Both
systems are supplied with a high quality soil temperature sensor.
