Why Choose This Semiconductor Tester?

All-in-One Testing Capability

This tool supports a full range of electronic components, including diodes, LEDs, BJTs, Darlington transistors, MOSFETs, JFETs, SCRs, triacs, diode networks, and digital transistors. It automatically recognizes component type and pin arrangement, so you can connect probes freely without complicated setup. It also identifies special built-in features such as protective diodes and parallel resistors, and can tell the difference between silicon and germanium components.

Reliable High-Precision Readings TRUST

Built with accurate measurement standards, the tester provides stable data for forward voltage, current gain, gate threshold voltage, and collector leakage current. It offers a wide measurement range, supporting hFE values up to 20,000, Vf from 0V to 4.00V, and leakage current detection as low as 10μA. Consistent testing parameters ensure results are repeatable and trustworthy every time.

Simple Operation & Clear Display

Designed with a straightforward two-button system, you can start testing with one press and browse results easily. The clear screen shows component type, pin layout, measured values, and status messages at a glance. It also features smart power control – automatically turning off after 60 seconds of inactivity, with a manual power-off option for extra convenience.
