Multi Measuring Instruments Co.

What Multi Measuring Instruments Co. does

Multi Measuring Instruments Co., Ltd. (マルチ計測器株式会社), founded in 1986 and headquartered in Tokyo, manufactures current sensors and related electrical measurement instruments, with operations spanning a headquarters in Tokyo (Nihonbashi area), a sales office in Osaka, and a repair/calibration factory in Noda City, Chiba Prefecture. The company employs 51–100 people and operates from a Japanese private corporate structure with no disclosed external investors. Its proprietary product portfolio centers on current sensing technology — DC and AC current sensors (split-core, through-hole, clamp configurations), CT sensors, clamp meters and clamp leak testers, insulation resistance meters (MIS-D digital and MIS-A analog series, JIS C 1302 compliant), and Io/Ior-method insulation monitoring devices. Distinctive technical capabilities include the MCLV-840IR, described as the world's first leakage current meter capable of measuring Ior on different-capacity V-connected three-phase circuits, Bluetooth-integrated multi-clamp leak testers (MCL-500IRVX) combining approximately six instruments into one unit, 4G LTE-enabled Io and Ior insulation monitors (LS-7S / LS-7SIRV) for remote monitoring, and Rogowski-coil flexible leakage meters for confined spaces. The company also distributes partner-brand field instruments from Megger, METREL, FLUKE, Fluke Networks, and T&D.

The business model is hardware product sales with repair and calibration services as an aftermarket revenue layer. Pricing is publicly listed and ranges from ¥4,400 to ¥105,000 ex-tax (e.g., MCD-107 pocket multimeter ¥4,400; HCL-7000DX-M Bluetooth high/low-voltage clamp meter ¥105,000), with orders under ¥30,000 incurring shipping charges and payment by bank transfer only. Distribution combines a direct website channel (multimic.com, available in Japanese, English, and Chinese, with inquiry/quote forms), a LINE Shopping storefront for selected SKUs, an annual JECA Fair trade-show presence, and routing of new enterprise customers without prior transaction history through 代理店 (agency/distributor) channels. Target customers are electrical construction and maintenance professionals, electrical equipment manufacturers requiring quality-control instruments, and solar PV installers/maintenance providers needing insulation and leakage measurement tools. Revenue figures, funding history, headcount trend, and named customer logos are not publicly disclosed.
