MRU-10 is a simple meter that allows you to measure grounding by the use of the technical method and to measure grounding resistance by the use of the 2-pole method. The instrument is easy to handle, resistive to interference, and highly accurate. MRU-10  is a basic device that allows checking the quality of the grounding system on the basis of the received measurement result. Its ergonomic shape, durable and firm housing, as well as big and clear display make this instrument ideal to use both in the field and most working environments. The device is simple to operate and intuitive. It is the best choice for electrical installations contractors, technicians, and professionals dealing with grounding measurements.

    UT261B Phase Sequence and Motor Rotation Indicator

    0 out of 5
    (0)

    UT261 series is used for determining 3-phase power phase sequence, missing phase indication, and motor phase  rotation (UT261B). UT261A and UT261B can measure AC voltage of 40~700V and 90~600V respectively.  These devices can operate in frequency range of 15~400Hz. UT261 are durable devices which can withstand impact from 2 meter’ s height. Test leads with protective tubing are included in optional accessories.
