What are the common units of pressure for air tightness testers, and what is the difference between Pa, kPa and MPa?
This paper introduces the working principle of the airtightness tester and common pressure units, including Pa, kPa, MPa, mmHg, bar, mbar, psi, etc., and explains the conversion relationship between pascals, kilopascals and megapascals. It also emphasized the importance of accuracy and detection speed of the airtightness tester, and mentioned the high precision airtightness tester of JCGK brand.
