Portable Soil respiration measurement
Portable soil respiration measurement for all soils including wet soils
Truly portable soil respiration system that offers researchers superior performance for a variety of applications including spatial distribution studies. The SRS-SD 2000 offers humidity control that allows it to measure wet soils.
Portable soil respiration measurement for most soils
Truly portable soil respiration system that offers researchers superior performance for a variety of applications including spatial distribution studies.
ADC BioScientific has developed the SRS series, the SRS-1000 and SRS-2000, two truly portable soil respiration systems that offer researchers superior performance for a variety of applications including spatial distribution studies.
The SRS-1000 is a truly portable soil respiration measurement system.
The ultra compact design, weighing only 2kg, makes the SRS-1000 suitable for even the most remote field locations. It will work continuously for up to 10 hours from a single battery charge.
It is light enough to be carried by a shoulder strap or even worn on a belt.
Working in an "Open system" operational mode means that the SRS-1000 provides highly accurate analysis in both low and high activity soils.
A graphical display allows easy monitoring of soil flux trends and the real time plotting of experimental curves.
The SRS-2000 features additional facilities for more sophisticated soil flux experiments.
Both CO2 and H2O can be automatically controlled inside the chamber. They can be controlled at single concentrations or automatically at sequential levels.
This allows soil flux to be determined at different CO2 concentrations, whilst the ability to dry air within the chamber prevents condensation occurring when working with soils of high moisture content.
For working with soils with extremely high levels of CO2 flux an extended 0-3000ppm CO2 range is provided with the SRS-2000.
The SRS-2000 features a number of expanded graphical functions further enhancing the versatility and interactivity of the system.
Despite these additional features the SRS-2000 weighs only 4.4kg and will work continuously for up to 16 hours from a single charge.
