Digital Insulation Resistance Tester (Megohmmeter) 1000V, Up to 5.5 GΩ
Safely test insulation resistance and electrical integrity with this high-precision digital insulation tester. Designed for professional electricians and technicians, it delivers reliable 1000V testing with automatic discharge, alarms, and clear digital readout.
This digital insulation resistance tester, commonly referred to as a megohmmeter, is designed to verify the insulation condition of electrical equipment, appliances, and circuits. It measures insulation resistance to ground and between conductors, helping identify degradation, leakage paths, and potential safety risks before failures occur.
The instrument supports multiple selectable test voltages up to 1000V, enabling accurate testing across a wide range of electrical assets. With a maximum insulation resistance measurement of up to 5.5 GΩ, it is suitable for testing motors, generators, transformers, cables, switchgear, appliances, lightning protection devices, and industrial electrical installations.
Additional functions include AC voltage measurement, continuity testing, polarization index (PI), and dielectric absorption ratio (DAR), providing a comprehensive diagnostic tool for preventive maintenance and compliance checks. Automatic discharge, overload protection, audible and visual alarms, and a backlit digital display enhance safety and usability in both field and workshop environments.
This tester is widely used in electrical maintenance, commissioning, fault finding, safety inspections, and industrial servicing, where accurate insulation measurement is critical.
