    Major Tech MT330 | Earth Resistance Tester

    Description:

    The MT330 is an ideal earth resistance tester for the measurement of earth rods and lighting conductors. Other ranges have been included such as AC voltage measurement up to 750V and DC voltage up to 1000V, plus a 200kΩ resistance range. The large backlit dual display LCD indicates the range measured as well as the battery voltage. The advanced circuit design permits the instrument to operate with minimum influence from earth voltage and earth resistance of auxiliary spikes. The double mould rubber injection housing ensures that the meter can handle the rough terrain when used in the field while performing earth tests.

    Features:

    • CAT IV 600V and CAT III 1000V
    • Earth Resistance 2000Ω
    • Earth voltage to 200V
    • Indicates if resistance of auxiliary spikes is within tolerance
    • Direct readout of the earth resistance on the LCD display
    • 750V AC & 1000V DC
    • Overrange indicator
    • Zero adjustment of leads
    • Data Hold
    • Overmould casing
    • Dual LCD with backlight
    • Ideal for earth rods and lightning conductors
