Theory

A respirometer is a device used to measure the rate of respiration of living organisms including microorganisms by measuring their rates of consumption of oxygen or production of biomethane or biohydrogen.

  • The gas that is finely generated from a reactor will turn into a bubble shape in a BRS cell which is filled with oil.
  • Cumulative volume of gas generated is measured by calculating the total amount of gas by fixing the bubble volume and multiplying by the number of bubbles.
  • The device can be used for both aerobic and anaerobic operations for wastewater studies.
  • The device can be also used for biogas production, biomethane potential (BMP) analysis, or green energy studies (CO₂, CH₄, H₂ and N₂).
  • Up to four devices can be connected to a common computer, supporting up to 32 channels.
  • The device uses temperature-based calibration to ensure accurate gas measurement.
  • After measurements, the time interval of gas production/consumption volume data can be changed by changing Cumulative Time in Data Convert.
  • An incubator or a water bath having magnetic stir plate can be used to maintain water temperature (0~50℃).
  • Measuring resolution (bubble volume) is very small (0.03 mL for BRS-800).
  • Bioreactors having volumes of 125, 250, 500, and 1000 mL can be used.
