UNI-T UT603 Inductance, Capacitance and Resistance Meter

When troubleshooting electronic circuits, accurate measurement of inductance, capacitance, and resistance is critical, yet many multimeters lack inductance capability. The UNI-T UT603 fills this gap with a dedicated LCR meter that handles inductors, capacitors, resistors, diodes, and transistors, making it an essential tool for electronics repair, prototyping, and education.

Who is it for

This meter suits electronics hobbyists, repair technicians, students, and engineers who need a reliable, portable instrument for component testing and circuit diagnostics. Its simple rotary dial and clear LCD make it accessible for beginners while offering the ranges professionals require.
