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

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