VARIOTEC 8 Detecting Water Leaks using Hydrogen Tracer Gas

VARIOTEC 8 FEATURES

VARIOTEC 8 IN USE

• The surface over the route of the pipe is searched for traces of gas using one of a selection of probes
• The VT8 detects gas down down to the lowest levels of parts per million, allowing you to pinpoint the smallest traces of gas and also up to the highest concentrations of volume percent levels (10,000ppm = 1 vol%) which ensures that you can hone right into the area of interest without reading overscale
• The large LCD display instantly responds to any changes in gas levels

• The escaping gas concentration is displayed both numerically and by a quasi analogue scale making it very clear where the highest readings are obtained
• The sensor used (there are two to allow more precise readings)and the measuring scale automatically switches between the most suitable range but can also be scaled manually to hone down the area of search

Why hydrogen?

Hydrogen, at 5% in a balance of nitrogen, is:

• non flammable
• non toxic
• non corrosive
• totally safe
• commonly used as a blanket gas in welding so is cheaply and readily available from all the standard gas suppliers
• has the smallest and lightest molecules so permeates all surfaces including concrete, tarmac, block paving and grass, rising quickly to the surface
• rapidly disperses in air allowing you to hone in quickly to the source
• unlike helium, which has also been used for some types of leak detection tracing, hydrogen is renewable and cheap;helium is finite and expensive

Variotec 8 locating probes

• Carpet probes for long stretches of smooth surfaces
• Bell probes which concentrate the gas for localising in undergrowth or on smooth surfaces such as kitchen floors
• Hand probes both telescopic and flexivle to reach into awkward areas
• Cone probes for localisation in bar holes you make in the ground

Charging and carrying

• Parts and accessories are stored neatly in the hard protective carrying case
• The VT8 may be charged directly from a 12 V cigar lighter socket in a vehicle or from the mains
• The detector can be charged whilst remaining in the case
