MK328 Transistor Tester Digital Meter Auto Detect Pins Measure Capacitance Inductance Resistance for Electronics Engineers Technicians DIY Hobbyists 3 Test Pens Included

Item Type: MK-328 Transistor Tester1. Key operation for automatic shutdown2. Battery operation is possible because the shutdown current is only about 20mA3. Automatic detection of NPN and PNP bipolar transistors, N- and P-channel MOSFETs, JFETs, diodes, dual diodes, unidirectional thyristors and bidirectional thyristors.4. Automatically detect the pin layout of the detected parts.5. Measure the current amplification factor of the bipolar transistor and the voltage of the base emitter threshold6. Darlington transistor can be identified by the threshold voltage of high current amplification factor.7. Measure the gate threshold voltage and gate capacity for MOSFET.8. Measure and display up to four decimal digit values in the right dimension. All symbols are surrounded by the probe number of the Tester.So potentiometer. If the potentiometer is adjusted to one of its ends, the tester cannot distinguish the middle pin from the end pin.9. The resistance measurement with resolution is 0.1° and can measure up to 50MΩ10. Can detect and measure a capacitor. It displays numbers with up to four decimal places in the right dimension. The value can be from 30pF to 100mF. The resolution can get 1pF.11. For those with a capacity value higher than 2μF equivalent. The serial resistance () has a resolution of 0.01Ω and displays two significant decimal digits.12. Up to two diodes are displayed in the correct order and diode symbol. In addition, the forward voltage is also displayed.13. The LED is detected as a diode; the forward voltage is much higher than the normal voltage. Two-to-one LEDs are also detected as two diodes.14. If the reverse fault voltage is lower than 4.5 V, the Zener diode can be identified15. Measure the capacity of a single diode in the opposite direction. If the base is connected and only one collector or emitter is connected, the bipolar transistor can also be analyzed16. Only

• [PROFESSIONAL GRADE ACCURACY] Engineered with premium 1° metal film resistors, this tester delivers laboratory-level precision with 0.1Ω resolution for resistance (up to 50MΩ) and 1pF resolution for capacitance (30pF-100mF). The advanced circuitry ensures reliable measurements of transistors, diodes, MOSFETs, and other components with unmatched consistency.
• [SMART AUTOMATIC DETECTION] Revolutionize your workflow with intelligent automatic component recognition that identifies NPN/PNP transistors, MOSFETs, JFETs, diodes, and thyristors in seconds. The system precisely maps pin configurations and displays all critical parameters including hFE, Vf, and gate threshold voltages without manual calculations.
• [COMPREHENSIVE COMPONENT ANALYSIS] Beyond basic testing, this meter evaluates crucial specifications like current amplification factors (up to 4 decimal places), base-emitter thresholds, and values. Specialized functions include Darlington transistor identification, Zener diode testing (up to 4.5V), and complete rectifier bridge analysis with a single connection.
• [INDUSTRY-LEADING DURABILITY] Built with components and a shock-design, this tester withstands demanding workshop environments. The optimized power system operates on standard batteries with ultra-low 20mA shutdown current, while the scratch-display ensures years of clear visibility.
• [MULTIFUNCTION TESTING SOLUTION] From measuring inductances (0.01mH-20H) to analyzing parallel components and LED characteristics, this all-in-one instrument replaces multiple single-function testers. The rapid 2-second measurement cycle (extendable for complex tests) and included test probes make it ideal for both professional and educational applications.
