For most high voltage test and measurement equipment, annual calibrations or performance checks are recommended to ensure proper operation and accuracy.

    The Calibration can be made by the third verification agencies which have cooperated with us for many years, such as National Center for High Voltage Measurement, Hubei Institute of Measurement and Testing Technology for electrical parameters & HV measuring systems for: impulse voltages, AC voltages, and DC voltages. All tests and calibrations are done according to EN17025 standards.
