    Kewtech KEW4200 Digital Earth Resistance Clamp Meter

    Use this Kewtech KEW4200 Digital Earth Resistance Clamp Meter to carry out earth resistance testing procedures without the need to use auxiliary earth spikes.

    Capable of measuring earth resistance levels between a range of 0.05 and 1200Ω with high accuracy, it can also be used to gain a reading of AC current levels. The KEW4200 includes large jaws which are designed for clamping directly onto a targeted testing application.

    With built in noise checking, the KEW4200 is able to filter out noise problems and maintain accurate results. These results are also able to be stored directly on the tester (it features memory for 100 readings) and other additional features unique to this earth resistance clamp meter include a buzzer function, data hold and a backlit screen.
