Gas-Tec MK5 FID

Gas-Tec is a portable Methane (CH4) and VOC gas detector for rapid survey and leak localisation. GPS, data and event logging allow survey teams to track progress and pinpoint areas of significant interest.

Gas-Tec is the next generation of flame ionisation detection. Offering users enhanced technology, Gas-Tec is the unique surveying solution.

The GES Gas-Tec portable Flame Ionisation Detector (FID) sensor can measure minute levels of hydrocarbons, allowing detection of levels from 1 to 10,000ppm of methane in less than 2 seconds as well as VOCs. Even gas leaks from distribution pipes located under main roads or highways can be quickly detected. Extremely portable, the Gas-Tec is shoulder carried allowing the independent probe to be positioned easily around valves and flanges.

Supplied with a refillable hydrogen cylinder (60 hours use), rechargeable lithium-Ion batteries (22 hours use), angled probe assembly, multi region mains charger, carry strap, quick start guide, user guide, filters and military grade carry case.

Industries and applications include: Landfills, Fire Brigade and Storage (Bulk / Fuel).




Gas-Tec is worn over the shoulder and has a wide range of probes and accessories for all applications.

Flame Ionisation Detector offering ppm level indication

  • Based on the tried, tested and trusted Gas-Tee engine
  • Simple and intuitive functionality utilising LCD and softkey technology
  • Rechargeable Li-lon battery offers more than 22 hours operation
  • Enhanced electronic controls reduce hydrogen usage
  • Full data and event logging with simple drag and drop download
  • GPS logging for accurate location report of leaks.

GPS: Enhances record keeping by assigning latitude, longitude and sea level to data readings. Users are also able to view the current location, offering the precise location to back-up crews for immediate leak management.

Data and event logging: Gas-Tee allows users the ability to download full survey information via the ‘drag and drop’ USB interface for survey traceability.

Intuitive functionality: LCD and soft keys offering  full sequence instruction, in-operation options, service and calibration  set-up and alerts.

Tried and tested: Based around the original Gas-Tee ‘engine’ detection method.The next generation  is therefore already proven, fit for purpose and suited to the trials of every day use.

Rugged and reliable: Ingress protected to IP54 for everyday use in all weather conditions.

Enhanced electronic controls: Offering extended battery and cylinder life. Pressure and flow transducers manage H2 and sample flow rates.
