The soil respiration measurement is used for the prognosis, inventory and control of remediation tasks, for biochemical degradation measurements of substances (pesticides, fungicides, fertilizer...) as well as to conduct toxicity tests.

This determination is possible with the OxiTop Control System and special measuring vessel tested in practice with much precision, easily and at a reasonable cost.

For soil with higher CO2 development, the measuring vessel MG 1,0 is recommended. It has a larger opening (approx. 100 mm diameter) and you will easily be able to use large-volume CO2 absorber vessels for the subsequent quantitative CO2 determination.

To measure the soil respiration according to the AT4 directive, there is an especially designed package that contains measuring vessel with a capacity of 2.5 l as well as a special CO2 absorber with indicator.


  • Different vessels for optimized adaptation to the application
  • Measurements for up to 99 days for special applications
  • Also suitable for AT4 measurements
