NRPA/NRPD Series high precision Standard voltage divider is developed as the standard high voltage measurement equipment for calibrating AC/DC voltage divider (digital high voltage meter) in high voltage measurement institute or high voltage laboratory. Its accuracy can be up to 0.1%, it can be used to test the high voltage divider with accuracy 0.2%, 0.5%, 1%, 1.5% or other lower accuracy of the electrostatic voltage meter, etc.
NANR Electric has committed to R&D AC/ DC voltage divider for long time, so far, the highest voltage level is 500kV, and the highest accuracy is 0.1%. Fully listening to the views of provincial metrology institutes, we have redesigned this series of products, which make it lighter and stability. All the core components are imported, through more than 30 kinds of strict screening processes to guarantee the excellent performance.
Overview
(2) Light weight good stability.
(3) High measurement accuracy.
