UNI-T UT501A Insulation Resistance Tester

The UNI-T UT501A is a versatile insulation resistance tester designed for accurate measurement of insulation resistance in electrical equipment and installations. It supports test voltages of 100 V, 250 V, 500 V, and 1000 V, with a measurement range up to 20 GΩ. The device also measures AC voltage (30-750 V) and low resistance (0.01-200 Ω), and includes advanced functions like PI (Polarization Index) and DAR (Dielectric Absorption Coefficient) for in-depth insulation analysis.

• Insulation resistance measurement up to 20 GΩ at 1000 V
• PI and DAR functions for detailed insulation condition assessment
• Low resistance measurement with zeroing function
• AC voltage measurement up to 750 V
• 2000-count LCD display with backlight for easy reading
• Audible and visual alarms for high voltage and continuous measurement
• Auto discharge and overload indication for safe operation
• CE and UKCA certified, compliant with IEC 61557

The UT501A is powered by 6 AA batteries, features a compact and durable housing, and includes test leads, crocodile clips, and a manual. Ideal for electricians, maintenance technicians, and engineers working on motors, cables, transformers, and generators.
