Description
The ZOYI ZT-MD1 LCR Tweezers Bridge Tester, available exclusively at Zigmotech, is a compact and highly accurate electronic measurement instrument designed for fast, one-handed testing of SMD components. It’s the perfect solution for engineers, technicians, and hobbyists who work with surface-mount devices (SMD) and need a convenient, portable, and precise tool for measuring resistance, capacitance, inductance, ESR, continuity, and diodes.
Combining professional-grade measurement accuracy with ergonomic design, the ZT-MD1 makes component identification, sorting, and validation effortless — whether in production lines, laboratories, or repair environments.
Key Features
1. All-in-One LCR Tweezers
The ZOYI ZT-MD1 functions as a complete LCR (Inductance, Capacitance, Resistance) measuring bridge combined with continuity and diode testing capabilities. Using precise gold-plated tweezer probes, it provides accurate measurements for both SMD and through-hole components with minimal contact resistance.
It automatically identifies the component type (R, C, or L) and instantly displays the value, polarity, and equivalent series resistance (ESR), significantly reducing testing time.
Measurable Components Include:
-
Resistors
-
Capacitors
-
Inductors
-
Diodes
-
LED Polarity
-
Continuity Checks
2. High Measurement Accuracy and Speed
The ZT-MD1 uses a high-precision auto-ranging measurement system, capable of detecting component values quickly and reliably. Thanks to its advanced signal-processing circuitry, it achieves accuracy levels comparable to benchtop LCR meters — in a portable handheld form.
Typical accuracy:
-
Resistance: ±0.5%
-
Capacitance: ±1.0%
-
Inductance: ±1.5%
This makes it ideal for component inspection, quality control, and educational applications where both precision and convenience are essential.
3. Intelligent Auto-Identification
The auto-detection feature allows the tweezers to automatically identify the type of component being measured and select the proper testing mode. It eliminates the need for manual switching, streamlining workflow and reducing human error.
For manual operation, users can also select the desired measurement type or test frequency, depending on specific needs.
4. ESR (Equivalent Series Resistance) Measurement
In addition to standard LCR functions, the ZT-MD1 can measure ESR values of capacitors, which is crucial for evaluating the quality and performance of electrolytic capacitors, especially in circuit repair and maintenance.
A high ESR often indicates capacitor degradation — and this device allows you to pinpoint those issues instantly, making it an essential tool for electronics troubleshooting and repair.
5. Continuity and Diode Testing
The integrated continuity tester emits an audible beep when resistance falls below the set threshold, allowing users to quickly check for open or short circuits.
In diode test mode, the instrument displays forward voltage drop, helping you verify correct polarity and identify faulty components.
6. OLED Display with High Readability
The ZT-MD1 features a bright, high-contrast OLED display that delivers crisp, clear readings even in low-light environments. It shows measurement values, component type, test frequency, and operational mode on-screen simultaneously.
The display is optimized for fast refresh and excellent viewing angles, ensuring that you can read data clearly during bench or field work.
7. Portable, Ergonomic, and Durable Design
Compact and lightweight, the Zoyi ZT-MD1 is designed for one-handed operation. The gold-plated tweezer tips provide excellent conductivity and minimal contact resistance, while the durable body offers a comfortable grip for extended use.
It’s powered by a rechargeable lithium battery, offering hours of continuous operation. The convenient USB-C charging interface ensures quick and universal recharging from any USB port.
Dimensions: Approx. 165 × 30 × 20 mm
Weight: ~90g
Whether in the lab, factory, or on the repair bench, the ZT-MD1 is built for precision and mobility.
8. Multiple Test Frequencies
Users can select between test frequencies (100Hz, 120Hz, 1kHz, 10kHz) to match specific component characteristics. This ensures accurate readings for capacitors, inductors, and resistors across a variety of applications — from low-frequency analog circuits to high-speed digital systems.
9. Auto Power-Off and Energy Efficiency
To extend battery life, the ZT-MD1 automatically powers down after a period of inactivity. Its low-power design ensures long operational cycles per charge, making it ideal for technicians on the move.
10. USB Connectivity and Firmware Upgrade
The ZT-MD1 supports USB connectivity for firmware updates, ensuring your device stays up to date with the latest calibration standards and performance enhancements.
