Advanced Component Detection Identify NPN and PNP transistors, capacitors, resistors, diodes and more with precise results to analyze components accurately. This helps you choose the right parts and diagnose issues quickly. Self Calibration Security The built in self calibration function ensures stable, reliable readings. When used with the included infrared remote control, you can perform measurements with added safety and consistency. Vibrant Colour Display A 1.8 inch TFT colour screen presents test results in clear and vivid colours, improving visibility and speeding interpretation. User Friendly Operation One button operation and automatic detection simplify testing, making the multi function transistor tester suitable for both beginners and experienced professionals. Use scenarios - At the workbench: verify transistors, diodes and passive components on motherboards or power supplies during repair. - Field troubleshooting: quickly identify component type and health on in car electronics or consumer devices. - Hobby projects: evaluate components in DIY kits and circuit experiments with minimal setup.
