Advanced Earth Resistivity & Geophysical Testing Solutions

Professional Geophysical Survey Services

Our advanced geophysical survey services utilize cutting-edge earth resistivity measurement technology to provide comprehensive subsurface investigation solutions for various industries and applications.

Earth Resistivity Meter 4point light 10W

Our high resolution earth resistivity meter 4point light 10W provides quantitative information about induced polarization (IP) of the soil. It measures the phase shift between the current injected into the ground and the voltage seen at the potential electrodes. It has adequate power to drive Schlumberger soundings up to L/2 = 1000 m.

ActEle – Active Electrodes

For electrical resistivity tomography we offer a chain of active electrodes (ActEle). ActEle is developed especially for connection to the earth resistivity meter 4point light 10W. It is used for multielectrode measurements. By default the electrode chain consists of 20 electrodes at a distance of 5 metres. Other distances (0.2 – 10 m) are available on request. The chain is extendable up to 255 electrodes.

Advantages

  • ✓Low power consumption, about 2 mW / electrode, active about 42 mW / electrode
  • ✓Extremely high input impedance due to an integrated amplifier: 1GOhm@1Hz
  • ✓Very low crosstalk between power and potential lines
  • ✓Ideal for critical conditions with high contact resistance
  • ✓Fast: with ActEle and 4point light 10W a 600 reading 2D profile can be measured within 10 to 15 minutes
