  • Insulation monitoring devices series HIG95 are devices for monitoring the insulation resistance in hospital applications.
  • In addition to the insulation resistance, the IMDs also evaluate the current and thermal load of the IT system and thus meet the requirements for monitoring the medical, isolating protective transformer.
  • There is also a number of monitoring panels, thanks to which the requirement for remote status signaling can be easily met. This is a series of MDS.
  • The IMDs are equipped with a display for displaying currently measured values. The display together with the buttons is also used to set up the device.
