The DC high voltage measuring device is a special instrument for
on-site measurement. It can test static negative pressure. The
voltage divider adopts balanced equipotential shielding structure,
and the internal insulation cylinder is completely sealed by the
quality of the electronic components, so that the whole device has
the advantages of accurate test, good linearity, stable
performance, reasonable structure, convenient carrying, visual
display, etc so it is the scene. The ideal instrument for
