Advantage of eEnery meter calibration device

1. Electronic program-controlled electric energy meter inspection device carefully researched and developed in accordance with the requirements of relevant standards and regulations.

2. Adopting the world’s advanced technology which provides high accuracy level, with simple and beautiful appearance, exquisite craftsmanship, complete functions and excellent performance.

3. High degree of automation. When verifying the electric energy meter, only need to manually participate in the watch, adjust the photoelectric sampler, and correctly design the parameters of the meter, all the verification items (including warm-up, creep test, start-up test, standard deviation determination, and basic error determination). It is automatically controlled by the PC and completed at one time. The calibration procedure can be in accordance with national regulations or can be customized by the user.
