GM328 Transistor Tester Frequency Tester PWM Square Wave LCR Meter Voltmeter Full Color Screen Graphics DIY Kit with Acrylic Case

The GM328 Transistor Tester is a versatile tool for testing various types of transistors, including NPN and PNP, Darlington, and Zener diodes.

With its advanced features, this tester can measure the common emitter current amplification factor, base-emitter threshold voltage, collector-emitter leakage current at cut-off, and much more.

The built-in protection diodes of power triode and field effect tube are also detected.

Additionally, the GM328 can test the gate-source conduction threshold voltage, on-resistance of the drain-source, and capacitance between the gate and source.

It can measure up to 50MΩ of resistance and has a highest resolution of 0.01Ω.

The equivalent series resistance (ESR) of a capacitor greater than 90nF can also be measured, with a resolution of up to 0.01Ω.

Furthermore, the GM328 can simultaneously measure the turn-on voltage of two diodes and display their positive and negative poles.

Light-emitting diodes are also detected and displayed as graphic symbols of diodes, with their turn-on voltage much higher than that of ordinary diodes.

Zener diodes with reverse breakdown voltage lower than 4.5V can also be detected.

With its wide range of features and high accuracy, the GM328 Transistor Tester is an essential tool for any electronics enthusiast or professional.
