What Cosmo Instruments Co. does

Cosmo Instruments Co., Ltd. (コスモ計器) is a privately held Japanese manufacturer founded in 1970 by Kiyoshi Furuse and headquartered in Hachioji, Tokyo. The company designs, manufactures, and sells air leak testers, pressure gauges, flow meters, helium/hydrogen/battery leak detectors, and complementary peripheral and analysis equipment, anchored by proprietary differential pressure sensor technology, laminar flow sensors, and mass flow sensors developed in-house. It also markets Cosmo Super Gel, an original sealing/stretching material used both in industrial sealing applications and in the COSMO Extube sports training consumer product. Cumulative shipments exceed 100,000 units across the air leak tester line.

The company operates an enterprise field sales model through 7 domestic sales offices and a network of 11 wholly-owned subsidiaries across 13 countries (China, Korea, Taiwan, Thailand, Malaysia, Indonesia, Vietnam, India, USA, Mexico, Germany, plus Brazil and Australia via local agents), supported by an in-house ISO/IEC 17025 accredited calibration laboratory in Japan and the USA. Products are made-to-order with standard 1–2 month lead times, and pricing is quote-based. It serves automotive OEMs and Tier 1 suppliers (Toyota, Honda, Nissan, Mazda, Subaru, Denso, Aisin, Jatco, Koito), medical device makers (Terumo, Olympus, Nipro), electronics manufacturers (Kyocera, Panasonic, Hitachi, Canon), gas and housing equipment firms (Noritz, Rinnai, TOTO), and food packagers (Meiji).

Revenue is generated primarily through hardware sales of testing and measurement instruments, supplemented by calibration, inspection, and repair services through 6 service offices and 14 nationwide service locations in Japan, plus peripheral equipment and consumable sales. The leadership transitioned to the third generation in November 2023 when Haruka Furuse became President, succeeding Tomoyuki Furuse who moved to Chairman. Recent strategic emphasis is on large EV battery assembly leak testing (LS-R902EV) and continued geographic buildout, particularly in China following the 2024 establishment of COSMO INSTRUMENTS (CHINA, JIAXING) CO., LTD.
