Professional Megohmmeter | Five High-Voltage Ranges in One Device
-
High-Efficiency & Versatile
A compact two-in-one design combining a True RMS digital multimeter and a high-voltage insulation resistance tester for fast, reliable measurements in electrical maintenance and troubleshooting. -
Five High-Voltage Test Ranges
Features selectable voltage levels: 50V, 100V, 250V, 500V, and 1000V for precise insulation testing across various applications. -
Auto Ranging & User-Friendly Functions
Equipped with auto-ranging, data hold, auto power-off, and a clear backlit display for error-free operation in different lighting conditions. -
Dual Safety & Durability
Rated to CAT II 600V and CAT III 1000V, with strong overload protection and robust construction suitable for demanding industrial and field environments. -
Enhanced Testing Capabilities
Additional functions include continuity buzzer, diode test, frequency measurement, live line detection, and earth resistance test—all in one professional-grade tool.
