B-Beep Diode Beep Tester 2025-03-07
B-Beep Smart Diode Tester
This practical device can test all types of PN junctions, like Silicon diodes/transistors, Germanium diodes/transistors, and even LED's. It displays the voltage drop across the junction on a small OLED display, and emts a different beep depending on the type of junction detected. A simple reverse polarity function saves you the hassle of having to reverse the probes when you want to test a device.
