Gossen-Metrawatt Insulation Tester, 1000V Maximum Test Voltage, 50V Minimum Test Voltage - M550P
This insulation tester is a battery‑operated instrument designed to measure electrical insulation resistance across a wide voltage range for field and workshop environments. It combines a digital and analogue display to present readings and supports testing with a 5mA output current, enabling assessment of insulation condition in installations where controlled test current and varied voltages are required. The unit is CE approved for use within defined safety categories.
Features and Benefits:
• *Made in Germany - including DAkkS calibration certificate
• 10000000Ω insulation resistance range provides high sensitivity for fault detection
• 5mA test current delivers controlled measurement for accurate diagnosis
• 50 to 1000V selectable test voltage covers low‑to‑high insulation verification
• CAT II, CAT III, CAT IV safety ratings permit varied‑site testing
• AA battery power enables portable use without mains dependency
