UT258A is well designed for on-line measurement of DC/AC leakage current and current below 600V, which adopts latest CT and digital integration technology. Slender clamp is very suitable for places full of concentrated cables (such as, electric power metering system, high-speed rail system, automobile circuit maintenance and so on). Non-contact measurement ensures operation safety. The meter has mini shape with high accuracy, stable performance and perfect functions.

Earth Ground Resistance Testers
MRU-30 Earth Resistance and Resistivity Meter
-
It allows to take the measurements of:
- earthing resistance using auxiliary electrodes,
- earthing resistance using auxiliary electrodes and clamp (for measurements of multiple earthing),
- earthing resistance using double clamps for measuring multiple earthing without underground connections.
- ground resistivity (Wenner method),
- continuity of equipotential bondings and protective
- conductors (meeting the requirements IEC 60364) with auto-zero function – with current 200mA.
Additionally:
- measurement of resistance of auxiliary electrodes RS and RH,
- measurement of interference voltage,
- measurement in the presence of interference voltage in the power network
- with frequency 50Hz, 60Hz,
- selection of maximum measuring voltage (25V and 50V),
- introducing the distance between the electrodes for the resistivity in metres (m) and feet (ft),
- memory of 990 measurements (10 banks of 99 cells each),
- calibration of clamp used,
- data transmission to the computer (USB),
- indication of battery state.
