Product Description
It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables, and electrical equipment. At the same time, it can output a variety of different voltage levels with the step-by-step voltage adjustment function (for example, the 15KV model can generate a 12KV level, which is more widely used).
It also has the functions of measuring DC voltage, AC voltage, absorption ratio, and polarization index.
It is a common and indispensable instrument for telecommunications, electricity, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises that use electricity as industrial power or energy.
