UNI-T UT603 Digital Inductance Capacitance Meter

UNI-T UT603 Digital Inductance Capacitance Meter

Manual-Ranging Component Tester with Transistor hFE Measurement

The UNI-T UT603 measures inductance, capacitance and resistance using straightforward rotary-switch range selection. Additional diode, continuity and transistor hFE functions make it useful for checking individual components during electronics repair, practical training and general workshop testing.
