REED R5002 Digital High Voltage Insulation Tester


This high voltage insulation tester is capable or testing voltages up to 5000V and measures insulation resistance up to 60GΩ. The R5002 performs a spot insulation test by applying a regulated and stabilized voltage to measure the amount of flowing current and then calculates resistance in order to evaluate insulation integrity.


  • Test Voltages of 500V, 1000V, 2500V, and 5000V
  • Measure Insulation Resistance to 60GΩ
  • Large backlit LCD display with analog bargraph
  • Timer function for insulation resistance measurements (1 to 15min)
  • AC/DC Voltage from 0 to 600V with Max/Min, peak and relative functions
  • Polarization index measurement (PI)
  • Dielectric absorption ratio measurements (DAR)
  • Max/Min, Peak, Relative value and Data Hold functions
  • Cat. IV 600V safety rating
  • Low battery indicator and auto shut off
