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.

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.
