Hoyt Electrical Instrument 6212A IN

The Hoyt 6212A IN Digital High Voltage Insulation Tester is engineered for professionals requiring accurate and reliable insulation resistance measurements across a wide voltage range. With 20 selectable test voltages from 500V to 10kV in 500V increments, this tester is suitable for evaluating the insulation integrity of transformers, motors, cables, switchgear, and other high-voltage electrical equipment.

Equipped with auto-ranging capabilities, the 6212A IN measures insulation resistance from 25GΩ at 0.5kV to 500GΩ at 10kV with an accuracy of ±3% of the reading ±1 digit. The large, high-contrast LCD display ensures clear visibility of measurements, even in low-light conditions, making it ideal for use in mining and other challenging environments.

The tester also calculates Dielectric Absorption Ratio (DAR) and Polarization Index (PI) automatically, providing comprehensive insights into insulation quality. Safety features include external voltage presence warning, overload protection, and a low battery indicator. The Ener-Save™ function extends battery life, and the auto-off feature conserves power when the device is not in use.
