A rechargeable lithium battery provides complete portability. An indicator light shows you when it's charging and when it's full.

Incredibly easy to use. The tester automatically identifies the component and begins the test with a single button press. It even features a self-calibration function to ensure accuracy.

Effortlessly tests NPN and PNP transistors, N-channel and P-channel MOSFETs, JFETs, IGBTs, diodes (including double and zener diodes), LEDs, thyristors, and triacs.
