SURLABA Insulation Resistance Tester, 0.1MΩ-10GΩ Megohmmeter with 50V~1000V Output Voltage, PI/DAR Testing, 100 Data Storage Voltmeter Megohm Meter for Motors/Cables/Transformers/capacitors

• 【Precise Insulation Testing】The SURLABA digital megohmmeter delivers precise measurements (0.1MΩ-10GΩ, accuracy ±（5%+10) ) with 2000 counts, making it ideal for testing transformers, motors, and cables. Its variable-rated output voltage switches between 50V/100V/250V/500V/1000V automatically discharge after testing, ensuring safe operation for electrical maintenance professionals.
• 【Dual-Function Voltage Tester】This versatile milliohm meter measures both insulation resistance and AC/DC voltage (10V-600V), eliminating the need for multiple tools. The large backlight LCD clearly displays readings, while the 100-data storage function lets you record and review measurements - perfect for field technicians and repair specialists.
• 【Enhanced Safety Features】Designed with automatic voltage discharge and low-battery indication, our insulation tester prioritizes user safety. The durable, dust-proof construction meets industry safety standards, with clear high-voltage warnings to prevent accidents during electrical system diagnostics.
• 【Smart Data Management】Store up to 100 test results and easily recall them when needed. The data hold function freezes readings for accurate recording, while the intuitive interface allows quick deletion of unnecessary data, streamlining your workflow for efficient electrical equipment testing.
• 【Professional Electrical Tool Kit Essential】From routine maintenance to complex repairs, this battery-powered megohmmeter is built for electricians and engineers. Its portable design comes with protective casing, making it reliable for testing switches, appliances, and industrial equipment.
