      <p id='ui6ws'><sup id='ui6ws'></sup></p>

        1105 ER   Earth Resistance Testers
        3 Wire (Analog)    
        1105 ER
         Capable of measuring earth voltage.
         2mA measuring current permits the testing of earth resistance without tripping eath leakage current breakers in the circuit under test.
         In addition to faciliating for precision measurement, test leads for simplified two-wire measuring system also are supplied as standard accessories.
         Battery operated.
         Battery life indicator.
         EN 61326-1 safety standard.
         Calibration performed with supplied test leads.
