Electronic Component Testers for PCB Repair & Diagnostics
ZOYI component testers are designed for detailed electronic component analysis, PCB troubleshooting, battery diagnostics and electronics repair. Compared with a standard digital multimeter, specialist component testers can provide more information about capacitors, inductors, semiconductors, SMD components and batteries.
Choose the Right Component Tester
- LCR Meters – measure inductance, capacitance and resistance, with supported models also providing parameters such as ESR, impedance and selectable test frequencies.
- SMD Testers & LCR Tweezers – compact tools for testing small surface-mount resistors, capacitors and inductors during PCB repair, prototyping and component sorting.
- Transistor Testers – identify and analyse compatible transistors, MOSFETs, diodes and other semiconductor components.
- Battery Testers – check battery voltage and internal resistance to help assess battery condition in cells, rechargeable batteries and battery packs.
LCR Meter or Digital Multimeter?
A digital multimeter is ideal for everyday voltage, current, resistance and continuity measurements. For more detailed capacitor, inductor and component analysis, an LCR meter or specialist component tester provides additional measurement capabilities.
