LCR T4 Digital Transistor Tester Diode Triode Capacitance ESR Meter is an all in one universal LCR Meter.it is NPN, PNP, FET, MOSFET, Transistor, Inductor, Resistor, Capacitor LED and Diode tester. This LCR T4 diode triode Capacitance best transistor tester automatic test the pin of a component, and display on the LCD. Can detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltage. This digital transistor tester measures the gate and gate capacitance of the MOSFET threshold voltage. This tester ESR digital can simultaneously measure two resistors and resistor symbol is displayed. Can measure the capacitance of 30pF-100mF, resolution 1pF.
