Accurate, Rapid and Reliable Measurement of Soil and Net Canopy CO2 Flux…. and Affordable
EGM-5 Soil Respiration System
At the conclusion of each measurement sequence, the results are displayed on a high resolution, touch display with outstanding readability under high sunlight.
PP Systems has long been recognized as a manufacturer of high-level scientific instrumentation for the soil sciences. For more than 30 years our instruments have been widely referenced in numerous, prestigious publications and articles. We offer a very affordable soil respiration system based on the NEW EGM-5 Portable CO2 Gas Analyzer and SRC-2 Soil Respiration Chamber. The SRC-2 Soil Respiration Chamber and CPY-5 Canopy Assimilation Chamber can also be used with our CIRAS-3 Portable Photosynthesis System and TARGAS-1 Portable Photosynthesis System for closed system measurement of soil respiration and net canopy CO2 flux.
The SRC-2 Soil Respiration Chamber connects directly to the EGM-5 console. It includes a fan for flushing the chamber prior to measurement and for sampling. It also includes an internal sensor for measurement of air temperature near the soil surface.
Soil CO2 Efflux
The SRC-2 Soil Respiration Chamber with built-in temperature sensor can be used with the EGM-5 and CIRAS-3 for easy, accurate and rapid closed system measurement of soil CO<sub>2</sub> efflux.
Dimensions: 150 mm (Height) x 100 mm (Diameter)
Optional collars (as shown in picture) are available from PP Systems for use with the SRC-2 chamber.
Net Canopy CO2 Flux
The CPY-5 can be used with the EGM-5 and CIRAS-3 for closed system measurement of net canopy CO2 flux on low lying vegetation.
Dimensions: 145 mm (Height) x 146 mm (Exposed Diameter)
Exposed Area: 167 cm2
It includes sensors for measurement of air temperature and PAR (Photosynthetically Active Radiation).
Soil Moisture & Soil Temperature
Our rugged STP-2 Soil Temperature Probe can be used to measure soil temperature. It is commonly used with our SRC-2 Soil Respiration Chamber.
Soil Temperature Range
The Hydra Probe II (Stevens Water Monitoring Systems, Inc.) features a “dielectric impedance” measurement principle and it can be used with the EGM-5 for accurate measurement of soil moisture and soil temperature from a single probe.
