LuxtronicsIt 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.
LuxtronicsThis frequency meter can measure the frequency parameters of continuous carrier signal (intercom, cordless phone) and digital signal (GSM, CDMA, PHS, wireless remote control, etc.), with signal strength indication.
BESTOne key automatic identification: 1kh true effective value, NCV induced voltage, AC and DC current, AC and DC voltage, zero fire line identification and resistance on-off.
