What Microtest Corp. does

Microtest Corp. (MICROTEST Corporation) is a Taiwan-based manufacturer of precision electronic measurement and test instruments, founded in 1993 and headquartered in New Taipei City. The company designs and produces a broad portfolio of benchtop and production-line equipment centered on automatic balanced bridge impedance measurement technology, covering frequencies from 10Hz to 50MHz with basic accuracy up to ±0.08% (typical ±0.05%). Its core product lines include LCR meters, impedance analyzers, capacitor analyzers, DC bias current sources (up to 640A), hipot/insulation testers, impulse winding testers, transformer testers, cable harness testers (including USB Type-C), motor stator/rotor testers, power analyzers, wireless charger test systems, DC power supplies, and multichannel LCR meters, supported by a comprehensive range of fixtures and PC Link software. Manufacturing is performed at owned factories in Suzhou, China (opened 2001) and Kunsan, China (opened 2013), with direct sales offices in India, Korea, and Malaysia, and an authorized distributor network covering more than 22 countries across Asia-Pacific, Europe, the Middle East, and Mexico.

Microtest generates revenue primarily through one-time hardware sales of these instruments and associated fixtures, software, and accessories, with quote-based enterprise pricing through direct field sales and regional distributors. The company targets four primary solution verticals: Electronics Component Manufacturers (passive component characterization for inductors, capacitors, MLCCs, wireless charging coils), New Energy / EV (high-voltage harness testing, magnetic components for ultra-fast charging), Power Electronics / Power Supply (efficiency, harmonic analysis, USB Type-C testing), and, to a lesser extent, Education/Research institutions. GTM is enterprise field sales supplemented by channel partners, with marketing concentrated on major trade exhibitions (electronica, TECHNO-FRONTIER, VIMF), YouTube technical content, and a LinkedIn presence. The company holds TUV ISO 9001 certification (granted 1999), multiple Taiwan R&D and innovation awards, a Dun & Bradstreet Taiwan Top 1000 Elite SME award (2025), and a portfolio of patents supporting its proprietary measurement architectures.
