Handheld Helium Gas Leak Detector MoLeTELL®
A new modality for leak detection!! Handheld Helium Gas Leak Detector
MoLeTELL®
Ideal for transitioning from wet tests and bubble tests
Instantly detect and reliably pinpoint the leak location
◆Ideal for switching from wet/bubble tests to Helium leak test
Reduce fluctuations caused by visual inspection. Prevents contamination and rust formation on workpieces, thereby enhancing quality control.
◆Instantly detect and reliably pinpoint the leak location
Features an ultrasonic sensor. Even when high-concentration gas is inhaled, it recovers rapidly from saturation, enabling continuous measurement.
