    UNI-T UT278A+ High Precision Digital Display Clamp Earth Ground Testers Clamp Ground Resistance Tester
    Description
    UT278A+
    Clamp Earth Ground Tester
    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. UT278A+ can also measure leakage current up to 20A. 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
    1. Wide ground loop resistance measurement range (0-1200Ω), which can meet most of the user's measurement requirements;
    2.32mm large jaws, can test various grounding levels and equipotential busbars;
    3. 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;
    4. User-defined HI/LO alarm limits;
    5. Data retention function for obtaining stable readings in places that are difficult to access;
    6. Time-saving storage function is convenient for users to consult the test data to draw a table report after measurement;
    7. With CAT III 300V safety level
