Overview
Hospitality Enviro Tech Winding Insulation Resistance Tester with precision design is suitable for testing the insulation resistance of most primary and secondary equipment such as cable and transformers. It is used to determine the initial insulation condition of the device. The tester can easily measure the absorption ratio and polarization index, which can eliminate human calculation error.
