Wide Insulation Resistance Range: Measures insulation resistance up to 2000MΩ, suitable for most low- and medium-voltage electrical systems. High Test Voltage: Supports insulation testing up to 1000V, providing strong capability for evaluating breakdown and leakage conditions. Digital LCD Display: Large, clear backlit LCD screen for easy reading of resistance values and test voltage even in dimly lit environments. Accurate Measurement: Stable measurement circuitry and digital processing help reduce reading errors and provide fast, precise test results. Multiple Test Applications: Ideal for checking insulation on motors, cables, switchgear, transformers, home wiring, industrial electrical installations, and includes safety protection, durable construction, simple operation, and portable design. Safety Protection: Built-in overload and high-voltage protection to help protect the instrument and user during operation. Durable Construction: Robust housing designed to withstand daily field use in workshops, factories, and on-site maintenance environments. Simple Operation: Intuitive controls, clearly labeled function keys, and quick test button for efficient testing with minimal setup. Portable Design: Compact and lightweight, easy to carry for electricians, maintenance engineers, and inspection personnel.
