Soil Gas Flux System

CO2 Flux System

CO2 flux system

Soil respiration is measured by placing a chamber of known volume by a robot arm on the soil, which measures the rate of increase in CO2 within the chamber. With this system, air is continuously sampled in a closed circuit and the soil respiration rate is calculated, displayed and recorded by the instrument. The air within the chamber is carefully mixed to ensure representative sampling without generating pressure differences, which would affect the evolution of CO2 from the soil surface.

Advantages of Echo’s CO2 flux system include:

 

  • Fast response time
  • Lithium battery power units
  • Low power consumption
  • Pressure
  • Humidity
  • Temperature
