Leak Tester for Automobile Parts
[ Image ] Leak Tester for Automobile Parts

A low-cost, space-saving, short-delivery, and compact packaged type leak tester.
Best suited for replacement of submerged-type inspection or differential pressure type inspection.

Major functions enabling accurate leak inspection are concentrated in one compact package. Functions can be selected to suit the customer needs, such as a workpiece to be inspected and cycle time.
  • A package for engine covers and a package for shock absorbers available
  • Accurate leak inspection possible without being affected by the temperature of workpiece or the temperature and humidity in the use environment. Inspection possible immediately after temporary washing or high-temperature washing.
