The Intertek certification verifies that the device meets the safety and performance requirements for refrigerant detection systems outlined in Annex LL of UL 60335-2-40:2022 Ed. 4 and CSA C22.2#60335-2-40:2022 Ed. 4. These standards apply to household and similar electrical appliances, including heat pumps, air conditioners, and dehumidifiers.
In December 2007, INFICON acquired Sigma Instruments Inc. [25] In February 2016, US based, InstruTech Inc., was acquired by INFICON. [26] [27] In October 2018, Final Phase Systems LLC, assets of a software developer, and Techno-Tools Corp., assets of a manufacturer of hand-held leak detectors, were acquired by INFICON. [28] [29]
Optimal detection distance varies and is influenced by camera lens size, resolution, field of view, thermal detection range and sensitivity, leak size, and other factors. The system's layers of filters and immunity to environmental elements, such as snow, ice, rain, fog and glare, contribute to false alarms reduction.
A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.
RGAs would also be used as sensitive in-situ leak detectors commonly using helium, isopropyl alcohol or other tracer molecules. With vacuum systems pumped down to lower than 10 − 5 {\displaystyle 10^{-5}} Torr—checking of the integrity of the vacuum seals and the quality of the vacuum—air leaks, virtual leaks and other contaminants at low ...
A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.
