FS-3080E Soil Respiration Rate Tester

FS-3080E Soil Respiration Rate Tester

1、 Product Overview

Soil respiration is the core process of carbon cycling in soil ecosystems, and is a key indicator for evaluating soil biological activity, root and microbial metabolism, and carbon balance in terrestrial ecosystems. The FS-3080E soil respiration rate measuring instrument is a high-precision scientific research instrument specifically designed for measuring soil CO ₂ flux. This instrument adopts temperature compensated dual wavelength infrared CO ₂ analysis technology, integrates synchronous monitoring of multiple parameters such as temperature, humidity, and photosynthetically active radiation, and can accurately and continuously measure soil respiration rate, providing reliable data support for climate change research, land use assessment, ecological restoration monitoring, and agricultural ecosystem carbon management.

2、 Technical principles

The instrument accurately calculates the soil CO ₂ release flux by measuring the rate of change of CO ₂ concentration over time in the soil breathing chamber, combined with the known breathing chamber volume and gas flow rate. The dual wavelength infrared analysis technology adopted effectively overcomes the influence of temperature drift, ensuring measurement stability and accuracy in complex outdoor environments.

3、 Functional Features
