The Sanwa PDM509S is a robust, lightweight, single-range analog DC insulation tester meticulously engineered for dependable performance in diverse electrical applications. This instrument combines intuitive analog display with critical safety features, making it an ideal choice for electricians, technicians, and maintenance professionals.

Key Features & Benefits:

• Precision Insulation Resistance Testing: Accurately measures insulation resistance up to 100MΩ at a 500V test voltage. This range is crucial for identifying potential insulation breakdowns in low-voltage electrical systems, motors, cables, and other equipment.
• High Accuracy: Boasts an accuracy of ±5% of full scale within its primary measurement range, ensuring trustworthy results for critical evaluations.
• Integrated Voltage Measurement: Beyond insulation testing, the PDM509S offers versatile voltage measurement capabilities, including:
  • AC Voltage (600V max): Ideal for verifying the presence of AC power or checking line voltages.
  • DC Voltage (60V max): Suitable for assessing battery levels or DC circuit potentials.
• Automatic Discharge Function: Enhances safety by automatically discharging any residual charge in the test circuit once the insulation resistance measurement is complete, preventing accidental shocks.
• One-Shot or Continuous Measurement: Provides flexibility with a push-switch for either quick spot checks or continuous monitoring of insulation values, adapting to various testing scenarios.
• Built-in Battery Check: Features an inner battery check range, allowing users to easily monitor the instrument's power status and ensure readiness for use.
• Robust Safety Compliance: Designed to meet stringent international safety standards, including IEC61010 CAT.III 600V and CAT.II 1000V, guaranteeing safe operation in professional environments.
• Compact & Portable: With dimensions of H144×W99×D43mm and weighing approximately 310g, its ergonomic design and lightweight construction ensure comfortable handling and easy transport for field use.
