Landfill and biogas

Geotech currently supplies the gas monitoring equipment for nearly 50% of UK anaerobic digestion, and we are market leaders in UK landfill gas monitoring and biogas analysis.



Groundwater is an important resource, so having accurate instruments for water quality monitoring is vital. Geotech supplies a range of instruments for groundwater monitoring and sampling.


Land remediation

Geotech has developed equipment for each stage of the remediation process, from identifying contamination to gas leak detection and the treatment of contaminated liquid.


CO2 monitoring

Our portable CO2 monitors are used in a variety of applications. Also measuring O2, temperature and humidity, they are versatile instruments for laboratories worldwide.


Medical gas

Verification of piped medical gases (N2O and O2) can be achieved with Geotech's G210 portable N2O analyser, and our G200 can be used for monitoring background levels of anaesthetic gases.

Medical gas

Coal mine methane

Geotech has developed gas monitoring products to optimise power generation from the natural gas released during mining, as well as for low concentration methane purposes.
