Soil Respiration Meter SRM-3051T (CAT#: STEM-OEM-0377-ZJF)

The Soil Respiration Meter is a key instrument for evaluating the carbon flux from terrestrial ecosystems by measuring CO₂ emissions from the soil. It monitors soil respiration and related parameters—such as CO₂ concentration, soil temperature, photosynthetically active radiation, air temperature, humidity, and gas flow—providing valuable insights into the biological and climatic factors affecting carbon cycles in soil. It is essential for environmental research and ecosystem studies.
