Máy đo điện trở đất EARTH HiTESTER 3151

For Maintenance of Electrical equipment (Grounding resistance meter, Voltage Detector)

EARTH HiTESTER 3151




Ground resistance meter 3-electrode measurement on the 3151 gives greater precision !
  • Wide measurement range for 0 to 1150 Ω, based on EN standard
  • Switchable measurement frequency to minimize the influence of harmonic earth voltage
  • Semi-dust-proof construction
