Multi-link air leak tester that anticipates the future of leak testing.
This machine is a leak tester developed under the new concept of multi-link compatibility, and it is a next-generation air leak tester that consolidates all the leak testing technologies that Cosmo Instruments has cultivated over many years. It features an easy-to-use color LCD panel, a compact and lightweight pneumatic unit, and high precision. Additionally, by adopting a field bus, it achieves a reduction in wiring by connecting the control panel and the pneumatic unit with a single dedicated thin cable. One control panel can control up to eight pneumatic units. 〇 Four Language Display Switching Function The display allows for the selection of four languages: Japanese, English, Chinese, and Korean. Please choose a language based on the region where the product will be used. 〇 Multi-Unit Control Function One control display can control up to eight pneumatic units. Each unit can be controlled simultaneously or individually. The pneumatic units have been designed to be compact, allowing for space-saving and reducing capital investment costs through multi-unit configurations.

Company information
The Air Leak Tester from Cosmo Instruments started with the automation of cylinder block airtightness testing in 1970. It is utilized in various fields such as automotive parts, gas, water supply, medical, electrical, electronics, and food industries. Since 1983, we have begun our overseas expansion in line with the overseas development of Japanese automotive manufacturers. Currently, we are conducting proposal activities and after-sales service activities similar to those in Japan from 24 locations in 13 countries. Recently, to respond to the electrification of automobiles, we have enabled leak testing of electrification components such as battery cases and inverters, as well as fitting tests for various power connectors, contributing to our customers' CO2 emission reduction efforts. Additionally, we have donated pressure measurement equipment to technical schools in South Asia and Southeast Asia to improve the quality of education, engaged in technical exchanges with local machinery manufacturers, and worked to enhance the industrial foundation through the production of high-quality leak testing equipment locally. We will continue to deliver the value of "quality" by applying our wisdom on-site for our customers and to contribute to the development of local communities.
