Soil respiration measuring instrument

Product introduction:

The soil respiration meter can simultaneously display the CO2 concentration, temperature and humidity changes inside the respiration chamber and the external photosynthetically active radiation intensity. It is widely used in agricultural ecological research, carbon source and carbon sink research, global climate change, land use change, ecological restoration research, soil microbial activity assessment, plant ecology research, insect respiration, root respiration and fruit storage.

Technical indicators:

CO2 analysis:

Dual-wavelength infrared carbon dioxide analyzer with temperature regulation, measurement range: 0-5000ppm, resolution: 0.1ppm; accuracy 3ppm. Carbon dioxide measurement is not affected by temperature changes, and is stable, accurate, and sensitive. The carbon dioxide difference acquisition can be completed within 1 second.
