Finding the cause of a leak or rather the point where it all started can be hard, however, having the right pieces of equipment with you will definitely help get the job done. There’s a lot of leak detectors on the market – automatic or manual, helium or hydrogen based but there is one in particular that I have found to be great in what it does: the MGD – 2002. One of the main reasons why this one is my favorite is due to the fact that it uses both hydrogen and helium. However, there is so much more to it.
- First and foremost, what I love about it is the battery – not just the type but the capacity of it too. The NiMH battery of the MGD 2002 can give you 8 hours of non-stop usage from a full charge. Water leak detectors are usually not very big on battery life but with this kit, you will be really set for the day.
- This device has provided me with very accurate results as its sensitivity can go to as low as 25PPM or 0.0025% concentration levels. It also comes with a tactile membrane keypad and a field replaceable moisture removing cartridge that’s built-in right into the wand together with a moisture indicator.
- The backlit LCD display can show a time-lapse bar graph and it offers you the ability to change either to automatic or manual mode. There is also a 3.5mm headphone jack in case you want to do some audible monitoring. The kit also includes a lightweight telescopic ground probe with a boot.
- With helium and hydrogen both being used for the tracer gas method, the penetration levels are greater than the ones of most water leak detectors that use only one, which is usually helium.
- You can see these water leak detectors being used in municipal water systems and also in the telecom industry, mostly with direct buried telephone cables, air pipe systems, splice cases, and underground ducted cables.
- You can also use them in aircraft systems, tanks and vessels, air, gas, and liquid piping systems, buried water services, and refrigeration systems. There are a lot of cases where you can see them being used in under slab or buried piping systems, secondary containment systems, and radiant heat flooring.
- Some unconventional applications include medical device testing, environmental testing, electronic chip doping, and checking if welds, seams, gaskets, and joints have been damaged or how well they are constructed.
