Wide Range of DetectionOur transistor tester is capable of detecting NPN and PNP transistors, capacitors, resistors, diodes, MOSFETs, thyristors, and batteries to ensure comprehensive testing for your electronic components. Self-Calibration and Zener Diode DetectionThe tester features self-calibration and can detect Zener diodes with ease, providing more accurate results and saving you time. Convenient Infrared DecodingAfter completing a test, use the included remote control to decode the results with infrared decoding technology that displays data codes and waveforms for easy interpretation. User-Friendly Design The one-button operation is simple enough for beginners to use while the automatic detection and shutdown function offers added convenience during busy projects. Colorful DisplayUnlike typical black-and-white displays on other testers, our device features a vibrant color display that makes it easy to read results even in low-light conditions.
