Air Leak Tester for Large EV Batteries LS-R902EV
Air Leak Tester for large EV batteries! Ideal for low-pressure leak testing of large, deformable EV battery assemblies with over 100 L!
The LS-R902EV realizes high-accuracy leak testing of large, deformable EV battery assemblies with over 100 L volume. - Equipped with a highly reliable differential pressure sensor - Two new features further enhance the accuracy of leak measurement for large-volume works - CISVAS Filter filters flow changes due to sudden deformation of the work - Ambient Temperature Compensation reduces false judgments caused by changes in ambient temperature * For more details, please download the PDF or contact us.

Cosmo’s Air Leak Testers began with the automation of cylinder block airtightness tests for engines in 1970. Our products are utilized in various fields including automotive parts, gas, water supply, medical, electrical, electronics, and food. In line with the overseas expansion of Japanese automakers, we began our own overseas expansion in 1983. We now have 24 sales and service offices in 13 countries. We are offering proposals and providing after-sales services overseas as in Japan. Currently, in order to support the electrification of automobiles, our products are being used for leak testing of parts for electrification such as battery cases and inverters as well as for fitting testing of electric power connectors. We are contributing to the efforts by our customers to prevent emissions of CO2. In various regions of South and Southeast Asia, we are donating pressure measuring equipment to technical schools to improve the quality of education and exchange technologies with local machinery manufacturers. We have been making every effort to help improve the industrial base through local manufacturing of high-quality leak testing equipment.
