BSIDE ESR02 PRO Transistor Tester SMD Components Checker Mega328 NPN/PNP Diode Resistor Inductor Capacitance ESR Meter with Tweezers

[Wide Application]: It is very easy to test plug-in and SMD devices, it can also be used to test different kinds of triodes, thyristors, MOSFET, enable to analysis the device type, the polarity of the pin, the output HFE, the valve voltage, the junction capacitance of the FET. [Automatical Identification]: Smart transistor checker is able to detect NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, thyristors, resistors, capacitors or other devices automatically. [2 POWER/TEST Button]: POWER/TEST button on both sides, you can operate it with your left or right hand. [Typical ESR Value Table]: There is a table "typical ESR value of electrolytic capacitor" at the back, provide a clear indication that you can quickly understand and use it. [Added Functions]: The transistor tester will be auto power off to save energy if there is no any operation within about 10 seconds. Large LCD display with backlight function for easy reading.
