This portable Insulation Resistance Tester is designed to help prevent hazards such as electric shock and short-circuits. Insulation in electrical devices, parts, and equipment used in industrial plants degrades over long periods of use. This instrument will help ensure maintenance and safety in homes, schools, buildings, factories, and more.
Application
Suitable for measuring electrical machinery, cable, electromechanical equipment, telecom equipment, electric power facilities, and other insulation resistance.
