Gas tightness testing is a sealing and waterproofing performance testing, which uses gas to detect whether there is leakage. Sealing performance testing is a broader concept, which uses any medium to test whether it can stop penetration or leakage.?
The difference between the two is:
Detection medium: Gas tightness testing only uses gas, sealing performance testing can use any medium.
Detection accuracy: Gas tightness testing is more accurate than sealing performance testing of liquids or solids, because gas molecules move fast and leakage is small.
Detection methods: There are many methods for gas tightness testing, such as direct pressure, differential pressure, flow type, etc. There are a few methods for sealing performance testing, such as microbial challenge method, color water method, and bubble release method.
The purpose of testing: The airtightness test is to ensure safety, reliability and economy, and the sealing performance test is to ensure the function, quality and effect.
On the airtightness testing equipment brand, there are many brands of airtightness testing equipment on the market, by national brands and imported brands divided into enumerated parts, these airtightness leak detector brand precision and have a certain degree of visibility, the following rankings are not in any particular order:
