Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Multi-Parameter Measurement: Measures AC/DC voltage (up to 600V), AC/DC current (up to 600A), resistance, capacitance, and frequency, with True RMS capability for accurate non-sinusoidal waveform readings.
  • Non-Invasive Testing: Features a large, adjustable clamp for easy, safe current measurement without disconnecting wires.
  • Safety and Convenience: Includes NCV (non-contact voltage detection), auto-ranging, a backlit LCD display, built-in flashlight, and data hold function for clear readings in diverse environments.

Key features

  • 1. Material Technology: Durable Construction with Ergonomic Design

    • With a rubberized ergonomic grip and high-impact plastic housing, you can achieve secure handling and protection against drops or impacts. ~30% better grip than standard plastic models*, ensuring stability during prolonged use.

  • 2. Interactive Design: Intuitive Multi-Mode Presets

    • With multi-mode presets (AC/DC current, voltage, capacitance, resistance, and frequency), you can switch functions quickly without complex setups. 40% faster mode selection than traditional models*, thanks to its user-friendly button layout and backlit LCD display.

  • 3. Performance Parameters: High-Capacity Measurement Accuracy

    • With a 600A/600V rating and True RMS measurement, you can handle industrial-grade currents and voltages with precision. Outperforms basic meters by 50% in non-sinusoidal environments*, ensuring reliable readings for complex electrical systems.

  • 4. Scenario Solutions: Versatile for Residential and Commercial Use

    • With a CAT III 600V safety rating and large clamp jaws, you can safely use it for both residential wiring repairs and commercial electrical tasks. Suitable for 80% more scenarios than entry-level models*, including car repair and HVAC diagnostics.

  • 5. Certification Standards: Eco-Friendly Compliance

    • With EPR certifications in Germany (WEEE/Packing) and France (Battery/WEEE/Packing), you can ensure eco-friendly disposal and meet strict EU environmental regulations. 100% compliant with regional recycling mandates*.

Supplier's note

  1. Three Technical Breakthroughs:

    • True RMS Measurement: Enables precise voltage/current readings in non-linear circuits (e.g., inverters), reducing diagnostic errors.
    • CAT III 600V Compliance: Exceeds industry safety standards for residential/commercial use, protecting users and equipment.
    • Integrated Flashlight + Hold Function: Combines convenience and accuracy in dark or hard-to-reach areas.

  2. Optimal Version Selection:

    • Base Model: Ideal for residential/hobbyist use (e.g., car repair, home electrical checks).
    • Advanced Model: Targets commercial electricians needing extended features like capacitance testing and USB logging.
    • Pro Model: Designed for industrial engineers requiring rugged durability (IP67) and wireless data transmission for real-time analysis.

With the Pro’s CAT IV rating, you can safely handle high-voltage industrial systems, while its waterproof housing ensures reliability in harsh environments. Pair this with Bluetooth connectivity to streamline data logging, reducing downtime during critical operations.
