Gas-Tec Data Sheet - .PDF file.

The Crowcon Gas-Tec portable hydrocarbon gas detector is designed for rapid leak survey and localisation applications.

Using the tried and tested Crowcon flame ionisation chamber, the Gas-Tec also features technology such as GPS, data and event logging.

The device allows survey teams to track progress and quickly pinpoint and record areas of significant interest.

Increasingly, gas distribution and infrastructure companies are focussing on reducing the number and volume of leaks along pipelines.

Leaks have cost, environmental and safety implications, so pinpointing and repairing them quickly is essential.

Storing survey reports and service and calibration records are also a more frequent requirement, influenced by health and safety regulations.

Finally, with many companies being forced to reduce personnel, there is an increased demand for products that require minimal training and set-up times.

Crowcon developed the Gas-Tec specifically to address these issues, including features to help companies minimise leaks quickly and efficiently, with minimal manpower.

GPS position logging, for example, enhances record keeping by assigning latitude, longitude and distance above sea level to data readings.

Users can also view their current location, offering the precise location to back-up crews for immediate leak management.

Another feature is data and event logging, allowing users to download full survey information for survey traceability using ‘drag and drop’ via a USB interface.

Weighing 2.4kg (without the gas bottle), the Gas-Tec is worn across the body and is ergonomically designed to sit comfortably while in use.

The LCD display and soft keys offer full sequence instructions, in-operation options, service and calibration set up and alerts.

Menu prompts guide users through start-up and shut-down procedures, reducing training requirements.

The device can also be customised, with users able to set preferences for features such as preferred units, display settings, date format and language.

Enhanced electronic controls increase battery and cylinder life, while pressure and flow transducers manage hydrogen and sample flow rates.

A service and calibration timer also reminds operators when maintenance is required, ensuring the unit is always operable and in optimum working condition.

The Gas-Tec also includes an optional ‘service lock’ facility, ensuring it cannot be used in the field while out of calibration.

Based around Crowcon’s original tried and tested Gas-Tec ‘engine’ detection method, this next generation model is already proven, fit for purpose and suited to the rigours of everyday use.

With a response time of less than two seconds, the Gas-Tec is calibrated to methane, with conversion factors for other common hydrocarbons available.

It has a detection range of 0-10,000ppm and is accurate to within +/-10 per cent.

Battery life is more than 22 hours, allowing continual use for a full shift.

Battery recharge time is 2.5 hours.

Supplied in a wheeled ABS impact-resistant case with a fitted foam insert, it is ingress protected to IP54 and can be used outdoors in all weather conditions.

Accessories include a trigger survey kit, an in-vehicle survey tool allowing detection at speeds of up to 30km/hour.

Probe assemblies are also available for all types of applications, including bore hole, straight probe, cup attachment and detection trolley.

Other useful accessories are available, such as vehicle chargers, earphones, spare hydrogen cylinders and a hydrogen filling panel.
