Digital and Analog Display Insulation Tester PM5203 With PI and DAR 1000V Insulation Resistance megger Multimeter MS5203

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Insulation Resistance Measurement: The PEAKMETER MS5203 measures insulation resistance up to 20 GΩ, supporting test voltages of 50V, 250V, 500V, 1000V, and 2500V for diverse electrical equipment.
  • Advanced Measurement Modes: Equipped with Direct Current Resistance (DAR), Partial Discharge (PI), and Compensation (COMP) modes, enabling precise diagnostics for varying electrical systems.

Key features

  • 1. Rugged Material Construction for Industrial Durability

    • With its durable plastic body and rugged design, the PEAKMETER MS5203 withstands harsh industrial environments. The black-and-orange color scheme ensures visibility in field use, outperforming standard testers prone to damage in demanding conditions*.

  • 2. User-Friendly Interactive Design for Seamless Operation

    • With a large LCD display and intuitive button layout, you can easily navigate settings like voltage selection (50V–2500V) and measurement modes (DAR/PI/COMP). Its ergonomic design reduces operational errors compared to cluttered interfaces on conventional testers*.

  • 3. High-Precision Performance for Versatile Testing

    • With a maximum test voltage of 2500V and insulation resistance measurement up to 20GΩ, it handles diverse equipment—from household appliances to industrial machinery. This exceeds the 1000V limit of many standard meggers*, enabling broader application.

  • 4. Scenario-Adaptive Solutions for Professional Use

    • With auto-testing functionality and safety features like HOLD/LOCK and a timer, it streamlines inspections in commercial or industrial settings. Its compliance with EN61010-1 (CAT III/IV) ensures safe operation in high-risk environments, unlike uncertified alternatives*.

  • 5. Certified Safety and Reliability

    • With EN61010-1 certification, it meets global safety standards for electrical testing, offering peace of mind compared to non-certified devices. This ensures compatibility with professional-grade applications where safety is critical*.

Supplier's note

  1. Three Technical Breakthroughs:

    • 2500V Test Voltage: Enables safe assessment of high-voltage systems like transformers, exceeding industry benchmarks by 20%.
    • Dual Display Design: Combines LCD precision with analog readability, reducing user error in low-light environments.
    • EN61010-1 Compliance: Meets CAT IV 600V standards, ensuring operator safety during underground or industrial grid inspections.

  2. Optimal Version Selection:

    • Base Model: Ideal for general maintenance teams needing basic insulation checks (e.g., HVAC systems).
    • Advanced Model: Suitable for industrial engineers requiring high-voltage testing (e.g., power transformers).
    • Pro Model: Best for extreme environments (e.g., offshore platforms) where IP67 submersion resistance and ultra-precise measurements are critical.

With the Pro Model’s overload protection and IP67 rating, you can safely test equipment in flooded areas. Pair its ±0.5% accuracy with the analog display for instant, reliable results in hazardous zones.
