Product Description

  • UT270 series can quickly and safely measure the grounding system without disconnecting circuit ground lines or the need of auxiliary electrodes.
  • It can measure resistance from 0.01Ω with a resolution of 0.001Ω.
  • UT275 can also measure leakage current up to 30A.
  • These clamps’double insulation design makes them durable tools for outdoor work and effective in blocking interference signals from the environment.
  • Grounding resistance measurement in electricity, telecommunication, meteorology, oilfield, architecture and industrial electric equipment
  • Low battery indication
Package Included:
  • 1 x UT278A Clamp Earth Ground Tester
