Smart Tweezers: A new Generation of Digital Multimeters

Smart Tweezers is a new patented design concept integrating a digital multimeter with a built-in gold-plated SMD probes and a display. This light weight device can be easily held by one hand. and is idealy suitable for component evaluation on a PCB or a production line and sorting of SMD components. Smart Tweezers dramatically reduces time necessary to troubleshoot or debug a PCB simplifying process of locating a faulty component.

The new model St-5 of the Digital Multimeter Smart Tweezers is powered by a rechargeable Li-Ion batteries with a USB Charger that virtually eliminates necessity of a battery replacement.


The integration of SMD probes and the display, combined with automatic recognition of a measurement mode (L, C, and R) and the best measurement range allow the user to focus on the component under test. As a result, testing, sorting and evaluation of components become much more efficient.

Inductance, Capacitance, Resistance

Primary display shows present reading of the main impedance component (L,C, or R). The secondary display (at the top of the LCD screen) shows present reading of the secondary impedance component, such as a parasitic resistance of the capacitor (effective series resistor ESR).

Continuity/Open Test

The Smart Tweezers is designed for a continuity test. The beeper sounds when a resistance reading is below a threshold, or to indicate an open circuit.

Durable Probes

Tweezers tips are made of gold-plated non-magnetic stainless steel.

Ergonomic Design and Convenient Controls

Smart Tweezers features a Navigation Controller Joystick allowing quick controls without going into the menu. By pushing the Navigation Controller Up, Right, Down or Left you can select a proper function or setting directly, without entering the menu as it was done in the previous version of Smart Tweezers.
