詳情介紹：
The MRU-105 and MRU-106 (for 60Hz) are portable meters for the earth resistance and earth resistivity measurement (Wenners method). The instruments can measure resistance using 2, 3, or 4 poles method. Measurements can be simplified using current clamps. The very high immunity for existing interference voltage AC + DC at which measurement is still performed: 24V (68V-p-p) but also measurement of existing interference voltage up to 40V is unique functionality of the meters. Moreover meters measure the resistance of the probes and calculate automatically the error coming from probe's resistances.
The meters MRU-105 and MRU-106 (for 60Hz) additionaly can be powered from Ni-MH batteries or standard C size, and the test results can be stored in the internal memory and transmited to PC via USB - cable.
MRU-105 Technical Specifications
 
  • Measurement of earthing resistance using a three- or four- pole technique:
    - ability to perform measurements of multiple earthing system using three-pole
    technique without disconnecting earth system measured (with the application of clamps),
    - supervision of the measurement conditions (eg. voltages, impact resistance measurement electrodes RH i RS and battery state/monitor)
    - high immunity of interference voltage.
  • Measurement of ground resistivity (Wenner’s method):
    - the earth resistivity measurement with the possibility to introduce the distance between electrodes, automatic calculation and displaying the resistivity.
  • Measurement of resistance using a two- or four-pole technique.
  • Built-in battery charger.
  • Memory for 300 measurement results with an ability to transfer the data to a PC.
