Clamp meters for measuring earth resistance directly on earth rods (STAKELESS METHOD) and compatible with MacrotestG series meters

T2100 is a professional clamp specially developed to evaluate resistance of earth rods with no need to disconnect any part of the system.

The inner part of the device is made of 2 jaws, one for current reading and the other for voltage generation. The voltage jaws generate a potential (E) on the loop during resistance (R) measurement. A current (I) is consequently generated on the loop and is measured by the current jaws. Based on the value of parameters E and I, the instrument displays the resistance R value calculated as their ratio. The value measured by the device can be used in case the single rods do not influence each other. This device complies with standard IEC/EN61010-1 in CAT III 600V, CAT IV 300V and it is the ideal solution for measurements to be carried out both in private and in industrial environments.
