Differential pressure decay works by pressurizing a part and measuring for a drop in pressure. Even if a part is sealed with no opening to pressurize, there are ways to use chambers for ingress testing. We also offer differential noise canceling technology for testing large flexible parts, like battery housings.
Ioniq wind leak testing is the best technology to use when leak testing battery pouches and motor coil coverings. ATEQ’s Ioniq or B28 electrical leak testers use safe low ionization voltages to ionize oxygen molecules in the air around the test part and display an insulation percentage to see if the part is within specification.
