Insulation Resistance Testers

Insulation resistance testers are specialized electrical instruments used to measure the resistance of insulation in cables, motors, transformers, and electrical systems. By applying a high DC voltage and measuring leakage current, these devices help evaluate insulation integrity and detect potential faults or deterioration.

Commonly known as megohmmeters or “megger” testers, insulation resistance testers are widely used in electrical maintenance, installation testing, and safety inspections across industrial, commercial, and utility sectors. They play a critical role in preventing electrical failures, ensuring system reliability, and maintaining compliance with safety standards.

With features such as multiple test voltage ranges, digital displays, data storage, and robust construction, insulation resistance testers provide accurate and dependable performance for demanding environments.
