Our Story
Incorporated in 2007 as a professional consulting and technical services company, K.H.R. Associates Inc. is focused on vacuum technique and technologies for a wide range of industrial applications, servicing Automotive, High-Tech, Gas & Oil, Power Generation, Environmental, Pharmaceutical, and Food Processing Industries.
As a recognized expert in vacuum techniques and technologies, we would like to state that only a perfectly maintained and tested (on subject of leaks) vacuum or pressure system can perform efficiently and, more importantly – safely… since for some equipment with low tolerances of leakage or cross-contamination the system integrity parameters are absolutely critical.
Thus, we consider HLD (Helium Leak Detection) as the most advanced, coming from the scientific community maintenance tool to detect, pinpoint and quantify leaks at precision in a range of 0.1 mbar x L x sec-1, using mass spectrometry methods to identify the presence of Helium at a molecular level.
Why Use Helium?
- Symbol: He
- Atomic Mass: 4.002602 u ± 0.000002 u
- Atomic Number: 2
- Electrons per shell: 2
- Electron Configuration: 1s2
Helium is a chemical element with symbol “He” and atomic number 2. It is a colourless, odourless, tasteless, non-toxic, inert and monatomic gas.
Based on its physical and chemical properties, Helium is simply the best tracer gas to detect, pinpoint and quantify leaks for a number of practical and safety reasons, since it is a non-toxic, inert, non-condensable and non-flammable gas, not normally presenting in the atmosphere at more than trace amounts in a range of 5 ppm.
Also, due to its such a small atomic/physical size (the only molecule of Hydrogen is smaller than Helium, but Hydrogen is not inert), the molecule of He is capable of penetrating/passing through the smallest leaks, created by some defects of materials, porosity, heat expansion processes, badly maintained installations – sealing, valving, piping, flanged and welded connections, etc… and then be catched by a Helium Leak Detector.
