The HHM-MG300 combines a
1000V insulation tester with a fullfeatured true RMS multimeter in
a single, compact instrument. The
HHM-MG300 wireless frequency
(914 MHz) is suitable for use in
US, Canada and Mexico. It is an
ideal instrument that can be used
in testing insulation of electric
machines, measure the insulation
resistance of transformer windings,
cables, electronic equipments,
electric facilities, and more.
