ESR02 PRO Digital SMD Transistor Tester

Wide Application

Our multi-functional digital transistor tester is perfect for a wide range of applications. It easily tests plug-in and SMD devices, as well as a variety of triodes, thyristors, MOSFETs, and more. With our tool, you can identify device types, determine pin polarity, measure output HFE, valve voltage, and FET junction capacitance efficiently.

Automatic Identification

Equipped with smart identification technology, our tester effortlessly detects NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes, thyristors, resistors, capacitors, and other devices. This ensures precise and hassle-free testing every time.

2 POWER/TEST Buttons

For added convenience, our tester features a POWER/TEST button on both sides, allowing you to operate it comfortably with either hand. This ergonomic design ensures seamless and efficient testing.

Typical ESR Value Table

For electrolytic capacitors, we provide a detailed ESR (Equivalent Series Resistance) value table on the back. This table serves as a clear reference, enabling you to quickly understand and interpret the readings.

Easy to Use

Our transistor tester includes smart power management features to conserve energy. It automatically powers off after about 10 seconds of inactivity. The large, backlit LCD display ensures clear visibility, even in low-light conditions.
