The Hipotronics model 7BT60 is a piece of portable 60 kV AC (Center Tapped) Dielectric testing equipment designed to test the integrity of vacuum interrupters in switchgear. The output (current limited to 10 mA) is programmed to raise voltage at a preset rate to the desired test level.LIGHTHOUSE technology detects closure integrity through the exchange of gas through container defects. From products stored at room temperature down to cryogenic conditions, LIGHTHOUSE analyzers enable reliable container closure integrity testing (CCIT) across a diverse array of packages and products throughout the product life cycle.
Checking integrity of vacuum interrupters • Vacuum interrupters installed in this period have far exceeded their manufacturer specified life expectancy. • Failure of a vacuum interrupter could result in unnecessary downtime and damage to surrounding equipment. Traditional testing methods • Vacuum integrity Pass or Fail test using high voltage ac test set.The best leak testing machine is Vacuum Leak tester for PET Bottles. The testing instrument efficiently measures the leak integrity of PET Bottles that can be examined with the help of high-pressure vacuum and ensures that the test sample is free from all types of leakage. Leak testing plays a crucial role in ensuring the integrity of packaged products, particularly in industries like food and beverage, pharmaceuticals, and cosmetics. A compromised seal can lead to: . Ensuring .
