Digital refractometer customers may not even remember that you are a portable digital refractometer. But it really allows you to see clearly how the test circuit works. This tester is an intelligent tester. This tester applies photoelectric pulse technology, single-chip computer technology, and reliable electromagnetic radiation resistance technology, coupled with precise and reliable speed/distance sensors, and can be used for various voltage levels of DC pulses.

Transformer testing equipment, transformer comprehensive tester, transformer testing instrument, filter testing equipment, digital high-voltage meter, intelligent transformer ratio tester.

Transformer comprehensive tester suppliers are used to test the transformation ratio and group of power facilities such as transformers, electrical equipment, components, and electrical equipment. The ratio tester can provide low voltage and high current testing, with a wide measurement range.

The main content of safety regulations and testing for transformers, electrical equipment, and other electrical equipment is to conduct DCV withstand voltage testing and leakage testing, based on the purpose of testing the leakage current, transformation ratio, and polarization index of the motor.
