UT510 series testers can measure insulation resistance of large transformers, generators, high-voltage motors and more. UT510 series can also measure PI, DAR and other important specifications. Measured data can then be analyzed through PC software. UT513A can produce test voltage up to 5kV.

Models in UT510 series: UT511, UT512, UT513A
