Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Electrical Measurement: Auto-range AC/DC current measurement up to 1000A with True RMS capability for precise readings in non-sinusoidal environments.
  • Multi-Parameter Analysis: Measures voltage (AC: 600V, DC: 1000V), resistance, capacitance, frequency, and includes non-contact voltage (NCV) detection for safety.

Key features

  • 1. Durable Material Technology for Safe, Non-Contact Measurements

    • With a robust, ergonomic plastic handle and conductive metal jaws, you can safely measure currents up to 1000A without disconnecting wires, eliminating the risk of direct electrical contact. This design surpasses traditional clamp meters requiring physical wire disconnection*

  • 2. Intuitive Interactive Design for Easy Navigation

    • With a large, high-contrast LCD display and user-friendly interface, you can effortlessly switch between measurement modes (voltage, current, resistance, etc.) and read results clearly, even in low-light conditions with the built-in flashlight. The display is 30% larger than standard models for improved visibility*.

  • 3. High-Performance Parameters for Versatile Applications

    • With a max AC current capacity of 1000A and True RMS measurement technology, you can accurately assess non-sinusoidal waveforms and high-power loads, outperforming basic clamp meters lacking True RMS capability. It also measures up to 1000V DC, catering to demanding industrial or commercial scenarios*.

  • 4. Scenario-Specific Solutions for Professional & DIY Use

    • With built-in flashlight, data hold, and max/min hold functions, you can troubleshoot electrical issues in dark environments and capture critical readings for long-term monitoring. Its versatility suits both professionals and hobbyists, offering quick diagnostics for home or industrial systems*.

  • 5. Safety-Certified Design for Reliable Performance

    • With compliance to safety standards for high-voltage environments (up to 1000V DC), you can operate confidently in diverse settings. The non-contact voltage (NCV) detection adds an extra layer of safety, preventing accidental electrocution during testing*
