Description
The Hioki IR5050 High Voltage Insulation Tester redefines precision testing for high-voltage systems. Designed for maintenance engineers and field technicians, it offers stable and accurate measurements up to 10 TΩ with selectable test voltages ranging from 250 V to 5000 V DC, making it suitable for testing transformers, motors, and power cables.
Built on advanced measurement technology, the IR5050 ensures stability and accuracy even in challenging environments. Its intuitive rotary knob interface simplifies operation, while its compact and lightweight build enhances portability. For enhanced durability, the unit includes a rigid IP65-rated carrying case that protects against dust and water, ensuring reliability during field operations.
Beyond standard insulation resistance testing, the IR5050 includes diagnostic functions such as Polarization Index (PI), Dielectric Absorption Ratio (DAR), and Dielectric Discharge (DD), providing deeper insight into insulation condition and system health. These automatic calculations streamline complex assessments into clear, actionable results.
The tester also supports step voltage and ramp voltage testing, allowing users to identify insulation breakdowns before they become costly failures. Safety is prioritized with CAT IV and CAT III ratings, ensuring secure operation during high-voltage testing. Features like a flashing MEASURE button, automatic discharge, and live circuit detection help prevent accidental activation and ensure operator safety.
For data handling, the IR5050 integrates with the Z3210 Wireless Adapter for Bluetooth connectivity, enabling seamless pairing with the GENNECT Cross mobile app. Users can visualize insulation states through time-series graphs, attach photos to reports, and export results instantly as PDFs. Additionally, USB connectivity supports data logging and direct Excel input for efficient documentation.
Whether you’re performing field maintenance, electrical diagnostics, or compliance testing, the Hioki IR5050 delivers unmatched accuracy, safety, and convenience — a professional-grade tool built for modern insulation testing.
