Gossen-Metrawatt Insulation Tester, 1000V Maximum Test Voltage, 0.100mΩ Insulation Testing Resistance - M507C

This insulation tester is a battery-operated instrument designed to assess electrical insulation resistance across a broad voltage range. It uses an OLED display for clear readouts and is intended for industrial and maintenance environments where insulation integrity measurement is required. The unit operates within common ambient temperatures and conforms to recognised electromagnetic standards for laboratory and workshop settings.

Features and Benefits:

• 1mA test current delivers controlled stress during measurements
• 40V to 1000V range enables low-to-high voltage insulation checks
• 0.100mΩ resolution allows detection of small resistance changes
• Battery powered with AAA NiMH support facilitates field use
• CAT II and CAT III safety rating protects operators on site

Applications

• Suitable for verifying insulation on distribution equipment
• Ideal for preventative maintenance in industrial facilities
• Used with portable test kits for on-site diagnostics
• Can be used for commissioning electrical installations
• Suitable for routine insulation surveys in workshops
