Helium Leak Detaction
For the 24/7 field services /NDT masspectrometry diagnostic we propose the best in class Helium Leak defectors by Leybold GmbH and Agilent (Varian) Technologies, capable of detecting, locating and quantifying leaks in a range of 10E-12 mbarxL/sec (scc/sec) in a vacuum mode and 10E-7 mbarxL/sec (scc/sec) in a sniffer mode.
Detection of combustible gases and refrigerants
To be provided by a sniffer type Model NGD268 leak detector, capable of detecting presence of combustible gases & refrigerants at the leaking gas concentration as low as 50 ppm. K.H.R. Inc. unique leak detection technology also allows the use of acetone vapors - a gaseous tracer media - to detect leaks for a specific range of rough-vacuum and pressure applications.
Thermografic Imaging
With 240x180 IR resolution with 2 MP visual (visible light) camera, 20Hz refresh rate and thermal sensitivity < 0.04°C, we are able to lay out a high-definition infrared image in full-screen temp measurement (-4°F to 662°F), as well as to capture images and videos to identify further the objects, being recorded.

Leak Detection

Helium Leak Detection is the most advanced technology, existing on the market and in our scientific-research community –  to detect, pinpoint and quantify various leaks, currently employed for a wide range of industrial, scientific-research and commercial applications/equipment with low tolerances of leakage or cross contamination.             

All our Helium Leak test procedures to be performed strictly in accordance with the ASME BPVC Code Section V, Article 10 guidelines, ASTM E499 Standard Industrial Practices and ISO 20484 Standards; also, any other special requirements and industrial standards  would also be considerable. Helium / Hydrogen leak Detection technology is also the most efficient way to detect leaks in Hydrogen-handling systems and facilities

Along with the Helium Leak Detectors, we consider the NGD268 Portable Combustible Gas Leak Detector as a complimentary and highly sensitive gas detector. It can be used as an additional instrumentation for a wide range of industrial applications to detect the presence of Hydrogen, hydrocarbon gases, isopropyl alcohol, halogenation hydrocarbons, ketones and other compounds such as gasoline, industrial solvents, lacquer, refrigerants, ammonia, acetic acid, etc., utilizing a hot-wire semi-conductor sensor at the detected gas sensitivity of < 50ppm.

However, we DO NOT offer / provide any inspections of commercial (household) natural gas systems, nor refrigerant-containing equipment and appliances.

In conjunction with traditional Helium Leak Detection techniques & technologies the SC240M IR thermal imager offers thermal, optical, fusion, and PIP (picture in picture) 4-image modes – the invisible infrared waves will pinpoint the source of problems in case of maintenance and troubleshooting of industrial equipment, verifying integrity of complex mechanical components and assemblies, using seven multiple color palettes to choose / optimize the ideal color scale for the specific application.

Thermographic imaging technologies are absolutely critical for identifying/diagnostic of leaks in all types of heat pumps; especially for locating and quantifying leaks in the ground source heat pump lines. 

At K.H.R. Associates Inc. we strongly believe that the combination of the proposed leak detection and diagnostic technique and technologies  would definitely resolve any of your problems related to equipment leakage or cross-contamination issues – please contact us:
