Air Leak Tester for Small Sealed Parts　　LS-R740(ZL)

This tester is ideal to test Water-proof components or finished products which require IP Protection Rating.The part to be tested is placed in a capsule and pressurized to measure the pressure change caused by leak flowing into the part.

Edge & Function

Easy-to-navigate and intuitive interface with simple menu configuration
Easy volume compensation when the tested part and the reference part have a volume difference
Influence of noise genarated in the test on the part can be compensated, reducing test time
User selectable multi-language capability: English, Japanese and Chinese
USB port for easy test data management
Closer placement fo sensor section to the target capsule
