LCR-T4 ESR Meter Transistor Tester Diode Triode

With this device, you'll be able to automatically to detect NPN and PNP transistors, n-channel and p-channel MOSFETs, diodes, thyristors, resistors, capacitors and many other components. It is also possible to measure certain characteristics of these devices as, for example, the current amplification factor of BJT or the gate threshold voltage of a MOSFET and much more.
