SRS-SD series Portable soil respiration systems Lightweight and compact Up to 16 hour battery life Highly accurate Enhanced data capture and output capabilities User-friendly Ideal for spatial distribution studies Soil respiration Superior field performance Rapidly rising atmospheric CO2 concentration and its potential impact on future climatic conditions is an issue of increasing global economic and political significance. Both the SRS-SD1000 and SRS-SD2000 consist of a programming console and a soil respiration chamber with an integral CO2 Infrared Gas Analyser (IRGA), enabling the fastest measurement responses of gas exchanges from the soil. Soil respiration or soil flux can be defined as the net CO2 production of a soil, largely as a result of microbial decomposition of soil biomass. The amount of gas exchange taking place is frequently used as an indicator of the "health" of that soil. The rate of soil flux is influenced by a variety of environmental parameters especially organic matter content, soil moisture and soil temperature. Natural biomass respiration from soil is a major carbon source. Understanding soil flux and its relationship with other sources and sinks within the carbon cycle are currently subject to increasing scientific scrutiny in relation to global climatic change. The systems work in the highly accurate “open system” mode, ensuring that there is no build up of CO2 concentrations inside the chamber that could potentially suppress soil flux. The miniaturised IRGA has a standard operating range of 0-2000ppm CO2, with a resolution of 1ppm. It has been designed with excellent stability and drift characteristics. All measurements are automatically compensated for atmospheric pressure, temperature and the effects of water vapour broadening and dilution. The graph below shows the excellent stability of CO2 measurements during a 36 hour diurnal soil flux/temperature plot using the SRS-SDRespiration and Soil Temperature @ 5cm 2000. Diurnal Soil 25 Soil temperature ADC BioScientific has developed the SRS-SD series, the SRS-SD1000 and SRS-SD2000, two truly portable soil respiration systems that offer researchers superior performance for a variety of applications including spatial distribution studies. The measurement of soil respiration is also important in bioremediation and pesticide impact research

High quality soil chamber design Both the SRS-SD1000 and SRS-SD2000 feature a high quality soil respiration chamber, specifically designed for short-term soil flux measurements. The chamber consists of a lower stainless steel collar and detachable upper compartment, together with a PAR sensor and a soil temperature sensor. Truly portable and easy to use Both the SRS-SD1000 and SRS-SD2000 are truly field portable and easy to use. They are battery operated, incorporating the latest in low power consumption technology enabling up to 16 hours of continuous use from a single charge. Great care...

SRS-SD1000 Ultra compact soil respiration system The SRS-SD1000 is a truly portable soil respiration measurement system. The ultra compact design, weighing only 2kg, makes the SRS-SD1000 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. Weighs only 2kg 10 hour battery life Integral CO2 chamber analyser High quality soil chamber Easy to use Graphical display Affordable research instrument Working in an “Open system” operational mode means...

Grass photosynthesis The rugged transparent construction of the upper compartment ensures that a true Net CO2 Exchange Rate is measured, taking into account any small plant material that may be photosynthesising on the soil surface. The SRS-SD systems may therefore also be used to measure ambient photosynthesis activities by whole small plants or turf grasses. The SRS-SD systems can be easily and quickly configured to display and record full photosynthesis data and calculations.
