Helium Detectors are used primarily in leak detection situations where sonic detection methods are not effective (inability to maintain pressure in a pipe, instrument or soil saturation) or the leak is minuscule. Instead of “listening” for the sound of escaping gas from the leak, the Helium Detector actually detects the leaking gas itself. Because Helium has a small molecular structure and rises it will often make its way to the surface very close to where the leak is. A Helium Detector identifies trace amounts of the gas and provides an indication to the user of its presence through an audible alarm and a LED bar graph.
Whether trying to detect a leak in a pipe or testing specialty equipment, our technicians are trained to accurately perform the job and pinpoint any anomalies. Our molecular gas detectors easily and quickly will pinpoint gas leaks too small to detect with soap solution. These units can detect helium leaks of 1 x 10 -5 cc/sec.
Some facts on helium gas that make it a prime candidate for detection:
- Helium is the second smallest molecule
- Helium is lighter than air so it will rise
- Helium is non-toxic, inert and only 5 parts per million in the atmosphere.
- Helium can travel through concrete, stone, carpet, carpet pad, tile floors, and wood floors (sheet vinyl is a little more difficult) making it a very reliable leak detection and testing tool.
