Electromagnetic Conductivity

Multi-depth Electromagnetic Conductivity Meters - CMD

The wide range of CMD electromagnetic conductivity meters is designed for depth surveys from 0.15 m to 60 m. This non-contact measurement method provides fast conductivity and inphase surveys under all field working conditions (also in very dry and glacial soil).

CMD - Main Applications

Geological exploration, geotechnical engineering, agriculture, archaeology, groundwater protection, environmental mapping, mineral exploration, metal object detection and infrastructure.

CMD Control Unit

Connection to the probe via a cable or via Bluetooth wireless technology . Five survey modes. Quick view of the mapping area (max. 15,000 points).

CMD - Various Models Available

CMD-MiniExplorer: three depth probe

Ranges 0.5/0.25 m, 1.0/0.5 m, 1.8/0.9 m for archaeology, agriculture and civil engineering, provides immediate assessment of the vertical gradient of conductivity.

CMD-Explorer: Three-depth probe

Ranges 2.2/1.1 m, 4.2/2.1 m, 6.7/3.3 m for a wide range of uses, with immediate evaluation of both vertical and horizontal conductivity changes.

CMD-MiniExplorer 6L: six depth probe

Ranges 0.3/0.15 m, 0.5/0.25 m, 0.8/0.4 m, 1.1/0.5 m, 1.6/0.8 m, 2.3/1.1 m for high resolution mapping and profile viewing.

CMD-Explorer 6L: Six depth probe

Ranges 0.9/0.45 m, 1.6/0.8 m, 2.4/1.2 m,3.7/1.85 m, 5.0/2.5 m, 6.3/3.15 m for high resolution mapping and profile viewing.

CMD-Tiny: probe with a depth

With range of 0.7 / 0.35 m for studies of objects very close to the surface in civil engineering, agriculture and archaeology.

CMD-1: Economical probe with a depth

With 1.5/0.75m range for archaeology, agriculture and detection of buried metal objects.

CMD-2: probe with a depth

With a range of 3.0/1.5 m, it is often used for corrosiveness risk assessment during pipeline construction and for construction site surveys.

CMD-4: probe with a depth

With 6.0/3.0m range with a wide range of uses (geological prospecting, environmental pollution mapping, raw material prospecting).

CMD-4/6: single depth

Variable depth range 6.0/3.0 m or 9.0/4.5 m for similar applications as CMD-4 with greatly improved range.

CMD-DUO: single depth

Probe carried by two people, variable depth range 15 / 7.5 m or 30 / 15 m or 60 / 30 m for surveying deeper structures (eroded areas, foundations, cavities).

Main features - CMD Electromagnetic Conductivity

The sensors carry 1, 3 or 6 receivers with excellent stability during changes in the surrounding temperature. This technology provides both high-resolution mapping of underground layers and graphical representation of the same in vertical profiles, giving very satisfactory results for a range of applications and tasks, whether the sensor is carried in the hand or on a vehicle.
Multi-depth range (0.15 - 60 m)
Standard or custom sensors (1 or 3 or 6 receivers)
Fast sampling rate (up to 10 Hz), good stability during outdoor temperature changes
Two Bluetooth communication channels (for the sensor or external GPS)
Real-time clock, quick view of the map of the surveyed area
Data download via cable or USB portable memory
One ​​control unit for all sensors (black and white or color display)
Measurement in manual or continuous mode with GPS
Easy to use, possibility of control by a mobile phone application
Powered by rechargeable Li-Ion batteries (2-3 days of work on a charge)
Lightweight and robust construction
