Electrical Multimeters – EMM

Electrical Multimeters – EMM

  • Measure and display more than 30 parameters of a three phase line with or without neutral. True RMS values.
  • All values can be read without making program changes.
  • Reduced size 96×96 mm. Flush mounting in panel.
  • EMM 5 and EMM 7 with ModBus communication.
  • Suitable for all electrical switchboards used in the industrial field for instruments, motors, generators, etc.
