B-stock Gossen Metrawatt M 540 C insulation measuring device 50 V 100 V 250 V 500 V 1000 V

Insulation tester

The insulation tester is designed for measuring insulation resistance in de-energized devices and installations with nominal voltages up to 1000 V. It is used to test the resistance of earthing conductors, protective conductors, and equipotential bonding conductors, as well as their connections and terminals. Thanks to the integrated indicator lamp in the test probe, the insulation resistance can be assessed quickly and easily. As long as the lamp is illuminated, the minimum insulation resistance values ​​according to VDE 0100 are met.

Key features:

• Test voltages: 50 V, 100 V, 250 V, 500 V and 1000 V
• Quick test with signal lamp: The lamp indicates compliance with the insulation requirements.
• Measuring ranges:
  • Insulation resistance: Up to 400 MOhm
  • Low resistance measurement: Up to 4 ohms
• Measurement category: CAT II 1000 V – suitable for measurement in electrical equipment and installations with lower risk (e.g. household appliances).
• Display: Analog – visually indicates the resistance.

Technical data:

• Protection class: IP52 (protected against harmful amounts of dust and against dripping water)
• Power supply: 6 x 1.5 V mono batteries
• Calibration: Factory standard (no certificate is issued, however a high standard of accuracy is guaranteed)
• Dimensions (L x W x H): 110 x 165 x 125 mm
• Weight: 1.2 kg
• Maximum test voltage: 1000 V
• Maximum insulation resistance: 400 MOhm

This insulation tester offers a reliable solution for testing insulation and earth resistance and is indispensable in many electrical installation applications.
