Aneng MH15 Insulation Resistance Tester is a versatile 2-in-1 digital megohmmeter and multimeter designed for testing the insulation of transformers, motors, cables, and home appliances. It is highly regarded as a budget-friendly professional tool that combines high-voltage insulation testing with standard multimeter functions like voltage and capacitance measurement. Key Features Four Test Voltages: Supports selectable output voltages of 100V, 250V, 500V, and 1000V, allowing you to tailor the test to various electrical components. Automatic Discharge: For enhanced safety, the device automatically drains residual high-voltage charge from the circuit after testing is complete. Multimeter Functionality: Beyond insulation, it measures AC/DC voltage (up to 1000V DC / 750V AC), capacitance, and resistance, and includes a diode test and continuity buzzer. 6000-Count Backlit Display: Features a large, easy-to-read LCD screen with a backlight for working in low-light environments. Measurement Lock: Includes a “LOCK” key for continuous insulation testing without needing to hold down the “TEST” button. Safety & Durability: Built with a silicone protective sheath to guard against drops and designed to meet EN61010-1 safety standards.
