Air Leak Tester for Micro Volume Parts LS-R740(SS)
Performs the highly sensitive leak test on micro volume parts.The parts to be tested is set on a fixture, and inside of the parts ispressurized to measure the pressure change generated by leak.
Air Leak Tester is the automatic leak detector detects any leaks by the minute change of differential pressure and conducts OK/NG judgment. Ideal to be built into a production line for a laborsaving and a quality control purpose
Variety ranges from F.S.10mL/min to F.S 500L/min are available. Promotes an automation and a laborsaving of the measurement
Helium Leak Tester adopts the new testing method and Helium Leak Tester adopts the new testing method and
All Manometer comes with a traceability. Wide range of Manometers, from a micro pressure (F.S. 200Pa) to a high pressure (F.S. 50MPa) are available
Peripheral instruments are used with Air Leak Tester in order to enhance its functionality and convenience
We determine the acceptability of the sounds and vibrations of products using our special analyses developed in-house.

Controller
Pneumatic Circuit Unit
Helps reduce measurement errors and false rejects due to part temperature effects.
Compensation graphs viewed on large LCD screen.
Easy setting for mapping of the graphs.
Temperature compensation mapping should be adjusted on the actual production line.
The temperature difference between the part and the environment is measured to carry out the Temperature Compensation according to the correlation between the temperature difference and measurement errors.
Post-cleaning leak tests, engine parts (cylinder head, cylinder block)
(a correlation should exist in the differential pressure between the temperature of Work and the applied air)
Example of Temperature Compensation Data
| Tested part | Oil pan (Whole) |
| Test pressure | 100kPa |
| Equivalent internal volume | 2500 mL |
| Leak specification | 10 mL/min |
| Test timers | Pressurization 22 secs. Equalization 3 secs. Stabilization 5 secs. Detection 3 secs. |
