Laboratory Single & Multi-Bottle Respirometers
This section presents the BM respirometers line, which are completely developed and manufactured by Surcis, with an exclusive design for management, modelling, research and training on biological municipal and industrial wastewater treatment systems.
They may be used to assess toxicity, oxygen requirement and provision on site, degree of treatment, loading rate, nitrification and many other relevant operational parameters.

Laboratory Pulse Flow Respirometers
They may be used to assess toxicity, oxygen requirement and provision on site, degree of treatment, loading rate, nitrification and many other relevant operational parameters.
This section presents Pulse Flow Respirometer systems, which are developed and manufactured by RSA and Challenge Technology
Multi-Bottle respirometers measure the gas evolution and rate of evolution from digesting samples. They are useful for assessing imported feed stocks, toxicity, and health of the digesting culture.
AER-800 Research Respirometer
The AER-800 Research Respirometer System facilitates the automated, precision measuring, and continuous recording of respiration rates for both aerobic and anaerobic lab-scale cultures.
We have also sold successfully to Yorkshire Water and Anglian Water. Many of the original analysers have been carefully maintained and are still running today, whilst we continue to develop, manufacture and supply new monitors.
Easy Setup & Flexibility
- The most user-friendly respirometer on the market
- Records both aerobic and anaerobic respiration rates
- Expandable in sets of 8 reactors at a time
Pulse Flow Respirometer systems; PF4000 & PF8000
A multi-bottle aerobic & anaerobic dedicated respirometer for the laboratory measurement of gas production rate or methane production rate in anaerobic environments.
The principal of operation is very simple, i.e. detecting gas pressure or production with the pressure change already being calibrated under standard conditions.
Each respirometer system comprises four elements:
- Reactor vessels, stirrers and temperature control.
- Pressure detecting module
- Interface module
- Computer
