Geotech supplies a wide range of water sampling, water quality and level measurement solutions. We are able to offer you a solution on how to sample, monitor, extract and separate contaminants from within your water.

Medical Gas

Verification of piped medical gases (N2O and O2) within medical, dental and veterinary environments can be achieved with our G210 portable N2O analyser, and our G200 is used for monitoring background levels of anaesthetic gases.

Land Remediation

Contamination can arise from a number of circumstances, including fuel spills and plant leaks.  Land remediation is a likely scenario in the development of brownfield sites and is subject to legislative standards.


We have over 30 years’ experience of monitoring gases and liquids on landfill sites, working closely with businesses to offer reliable and sophisticated gas analysers, gas monitoring systems and data management software.

CO2 Monitoring

CO2 occur naturally in air at approximately 400ppm, this increases in offices and buildings, especially if poorly ventilated, because of this you cannot zero calibrate the CO2 value on Geotech analysers as this would cause a negative offset and false reading.
