Envco – Environmental Equipment

Gas-Tec is a portable gas detector for rapid survey and leak localisation. GPS, data and event logging allow survey teams to pinpoint and report on areas of significant interest. Gas-Tec senses hydrocarbons through the use of flame ionisation detection offering an extremely fast detection speed of less than 2 seconds.

Flame Ionization Detection (FID) is the fastest, most sensitive and accurate way to detect concentrations of hydrocarbons such as methane, butane or hexane.The FID process uses a hydrogen flame to burn hydrocarbons in an air sample then counting the ions produced by the burnt sample.The instrument then displays an accurate measurement of the concentration of hydrocarbons present in the sample.All sam¬ples are destroyed as the measurements are generated.This process takes place in a specially designed chamber.

Standard features
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-Tec 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-Tec ‘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.
