GM328 Transistor Frequency Tester PWM Square Wave LCR Voltmeter Graphic DIY Tool:
$13

Specifications:
This is a multifunctional transistor tester that can automatically detect NPN and PNP transistors, field effect transistors, diodes, double diodes, thyristors, and automatically recognize transistor spikes, which can also be used as a square signal and PWM signal generator.
Digital LCD display design make it easy to read, which can also display measurement data and graphics.
Rotary switch control and button measurement function make it easy to use.
The main chip is DIP, which is convenient for electronic enthusiasts to DIY or update the main chip.
Use 9V battery(not included) or DC power supply(DC 6.8-12V).
It can automatic shutdown and the shutdown current is only about 20nA.
It can be used to test NPN and PNP transistor common emitter current amplification factor, base-emitter threshold voltage, off-collector-emitter leakage current.
Support 2 resistance measurement and display its positive, negative and pass voltage.
The maximum resolution of resistance measurement is 0.01Ω, and it can measure up to 50Ω.
It can automatically test the pin of the component and display it on the display.
Moreover, it can measure the threshold voltage and threshold capacitance of field effect transistors.
This tester can be used as a signal generator and frequency meter, the frequency range is 1Hz-2MHz, and it can generate 1 degree to 99 degrees PWM(pulse width modulation) signals.
