Certified calibration gas, available in either 58 litre or 110 litre gas canisters, are supplied with the Geotech
calibration kit. Please refer to the Geotech website www.geotechuk.com for further information.
The regulator supplied with the calibration kit is pre-set for flow rates and pressure that are factory set.
If you are using a non Geotech supplied regulator, please ensure you use pressure regulation and that it
does not supply any greater than 200 mbar pressure.
Gas analyser
For the GEM5000 gas analyser the calibration options can be found by selecting the ‘Menu’ key followed by soft-
key ‘Operation Settings’. Select soft-key ‘1’ for ‘Gas Check’ and the menu below will appear. From here, select

Calibration processes – best practice
The following bullet points and process diagrams outline the calibration steps and best practise when calibrating
your GEM5000.
Ensure that you are regulating calibration gas down to below 200 mbar pressure, if you’re not using a
Geotech regulator. The use of a pressure relief valve is also highly recommended.
When calibrating, it is recommended to use a calibration mixture close to the levels you are trying to
