The 5877D can be used for measuring insulation resistance of insulating materials and various electric equipment such as Power transformers, electric motors, cables, and switches and can be used for measuring their absorption (R60s/R15s) and polarization index (R10min/R1min).


  • 1000 / 2500V / 5000 / 10000V high test voltages, test insulation resistance range up to 5000GΩ.
  • 240 X 128 Large LCD Display, High Resolution, Easy to read.
  • Display real time terminal Voltage, Leakage Current & Insulation resistance.
  • Automatic display and record R15s, R60s, R10min, R60s/ R15s and R10min/R1min manually record measurement at other test time.
