Vacuum leak testing is the principal leak test method for testing sealed parts that could have leakage from an external source into their housings and casings. Prime candidates for vacuum leak testing include:

• Underwater sensors or housings
• Outdoor electrical housings
• Sealed components
• Components associated with vacuum sources

Vacuum leak testing functions in a similar, but essentially opposite, manner as pressure decay testing. Quality first supplies a full line of vacuum leak test instruments that utilize innovative technology to deliver reliable, repeatable solutions to leak testing challenges.
Vacuum leak tester is an economic and proficient device that adds quality control measures to your packaging applications.
