This is a cost-effective and widely used transistor detector. You can use it to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, triac and battery etc. It can also be used to detect infrared wave forms. 

It can be widely used to detect NPN and PNP transistor, capacitor, resistor, diode, triode, N-channel and P-channel MOSFET, IGBT, JFET, triac and battery etc.
It also can detect zener diode and has the function of self-calibration.
After detection, align the infrared remote control with the "IR" light, then press the button in the remote control, if the detector successfully decode it, it will display the data code and infrared wave form.
One button operation, automatically detect and shutdown, and you can press the multi-functional button to close the detector too.
Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly.
Not like the usual black and white display, this detector will show results in color.

    Easily replaces a multimeter. Charges via USB Easy to use. I did not manage to get the infrared part of the system to work.

    Hello, this small tool for detecting various triac capacitor Zener diodes works well ... As for the BJT transistor, the random results of the Zener diode and the triac The switch is good. This is easy to say. It can pass.
