Pressure Units and Air Tightness Leak Rate Calculator

Free Leak Rate Calculator to make airtightness testing easy and efficient

This article describes the importance of gas-tightness testing, provides basic concepts of leakage rate and five common methods of calculating leakage rate, including the pressure decay method, the mass flow method, the tracer gas method, the pressure drop value conversion method and the foam method. Meanwhile, the free leak rate calculation tool of Precision Engineering Airtightness is recommended to simplify the airtightness testing process.

Temperature compensation data comparison

Airtightness tester NG parts test qualified? Reveal the influence of temperature on the test

This article discusses the influence of ambient temperature on the airtightness test results, revealing that temperature changes may lead to the misclassification of unqualified products as qualified. The article emphasizes the importance of temperature control and proposes strategies such as adopting high-end testing equipment, establishing a standardized testing process and regular calibration and maintenance to improve the accuracy and reliability of airtightness testing.

Leakage Rate Flow Rate Units

Must Read for Engineers: A Guide to Converting Leakage Units in Airtightness Testing

In airtightness testing, leakage is mainly measured by pressure unit (Pa) and flow unit (ml/min, sccm). Precision Engineering Gas Tightness Instrument supports dual-mode switching and intelligent judgment. Choosing the right unit needs to consider the test object, industry standards and testing accuracy, multi-unit display to help improve the quality of manufacturing industry.
