Tsuruga Electric Corporation

What Tsuruga Electric Corporation does

Tsuruga Electric Corporation (鶴賀電機株式会社) is a privately held Japanese manufacturer founded in 1954 and headquartered in Osaka. The company designs and manufactures industrial measurement instruments, organized across four primary product categories: signal-conditioning transducers (DC, RTD, thermocouple, AC, and power transducers in 7200, 7500, 7600, and 7920 series configurations with response speeds as fast as 150µs and accuracy within ±0.1% to ±0.3% of span), electrical safety testing equipment (insulation resistance meters, withstand voltage testers from 1kV to 10kV, and a distributed comprehensive winding tester), Wet Bulb Globe Temperature (WBGT) heat illness prevention instruments, and digital/analog meters and display panels including explosion-proof and waterproof variants. The underlying technology stack centers on precision analog signal conditioning, multi-protocol industrial communication (notably the Model 2601 Modbus converter added in 2024), and in-house JCSS-accredited calibration with CE/EMC test capability and ISO 9001/ISO 27001 quality and information security certifications.

The company serves a horizontally segmented industrial customer base across heat-safety monitoring for workplaces and construction sites, industrial process control and instrumentation, photovoltaic and renewable energy system monitoring, and electrical safety compliance testing. Its customer portfolio includes reference installations with public institutions such as Osaka Prefectural Government and recognition by the National Institute for Environmental Studies. Revenue is generated almost entirely through B2B direct sales of hardware, conducted via the Osaka headquarters, regional offices in Nagoya and Yokohama, and a website-based catalog and quotation system. Pricing is quote-based and not publicly disclosed; the model is transactional unit sales supplemented by calibration and repair services. Distribution is augmented by partnerships with Electronic Control International (winding testers) and Japan Lightning Research Vector (surge protection devices), which broaden the catalog without internal R&D in those categories.
