ANENG MH12 Insulation Resistance Tester – 1000V Megohmmeter with PI/DAR, AC/DC Voltmeter & Data Storage

product details ANENG MH12 Insulation Resistance Tester is a professional-grade digital insulation resistance tester (megohmmeter) designed for measuring the integrity of insulating materials in motors, cables, transformers, and other high-voltage electrical equipment. It combines a wide measurement range with automated health checks like Polarization Index and Dielectric Absorption Ratio. Key Features - Variable Output Voltages: Select between 50V, 100V, 250V, 500V, and 1000V to match different testing standards and equipment requirements. - Extended Measuring Range: Capable of measuring insulation resistance from 0.1MΩ up to 10GΩ, providing deep insight into potential leaks or aging. - Automated Calculation (PI & DAR): Automatically calculates the Polarization Index (PI) and Dielectric Absorption Ratio (DAR) to determine if insulation has been affected by moisture or heat aging. - Large Digital Display: Features a 2000-count HD LCD with a bright backlight and an analog bar graph for quick visual trend analysis. - Enhanced Safety Design: Includes an automatic voltage release function that safely discharges the circuit after testing, plus a red LED warning light for high-voltage output.
