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
