Grounding resistance measurement in electricity, telecommunication, meteorology, oilfield, architecture and industrial electric equipment

  • UT270 series can measure resistance from 0.01Ω with a resolution of 0.001Ω. UT278A+ can also measure leakage current up to 20A.
  • Wide ground loop resistance measurement range (0-1200Ω), which can meet most of the users measurement requirements;
  • 32mm large jaws, can test various grounding levels and equipotential busbars;
  • AC current measurement range 0-20A(UT278A+ only), and can detect leakage current below 300mA, can be measured without disconnection, which is very suitable for system fault diagnosis;
  • User-defined HI/LO alarm limits;
  • Data retention function for obtaining stable readings in places that are difficult to access;
  • Time-saving storage function is convenient for users to consult the test data to draw a table report after measurement;
  • With CAT III 300V safety level
