EM 4055

EM 4055

The MTD-20KWe & EM 4055 digital earth testeres allows for the measurement of Earth Resistances and Soil Specific Resistivity, and also the spurious voltages caused by parasitic voltages present in the soil. An internal current generator injects alternated current on the soil through an auxiliary rod. The voltage generated over the earth resistance is measured by the apparatus, and the resistance value is evaluated. The test current is automatically regulated.

Features

  • Earth resistance measurement
  • Ground resistivity (Wenner´s method)
  • High spurious voltage rejection
  • Spurios voltage measurement
  • 0.01 Ω resolution
  • Up to 20 kΩ resistance range
  • Auto-range
  • Built-in memory
  • Built-in printer (optional)
  • USB interface
