A challenge to cutting-edge technology Semiconductor Test SystemGeneral-purpose System

We have many products such as testers which can quickly and accurately measure electrical characteristics of the transistor or the FET and testers which can measure transient thermal resistance of the transistor.

LCR Meter

LCRThe LCR Meter is a instrument that measures electric parameters such as inductance, capacitance, resistance and impedance. Frequency and signal level are variable. >> more

Curve Tracer

CurveThe Curve Tracer allows the operation to measure static characteristic curves of semiconductors such as transistors, FETs, thyristors, diodes and ICs. We have... >> more

Coil Tester

CoilThe Coil Tester can measure the number of winding, layer short and core material by comparing vibration waveforms of the applied voltage to the standard... >> more

Automatic Coil Test System

MakiThis system combined with the LCR meter is capable to measure the inductance and the dissipation factor of the coil when DC current... >> more
