LandMapper ERM-04

LandMapper ERM-04 measures electrical resistivity or conductivity of soils and related media for express non-destructive mapping and monitoring of agricultural fields as well as construction and remediation sites. In a typical setting, a four-electrode probe is placed on the soil surface and an electrical resistivity or conductivity value is read from the digital display. The device measures electrical resistivity or conductivity in a surface soil layer of the depth from 2 cm down to 20 m, which is set by varying the size of a four-electrode probe.

• Compact and portabledesign (weights only 250 g without the probe)
• Fast (one measurement takes 4 sec.)
• Accurate (automatically accounts for spontaneous potential arising from grounding of the electrodes)
• Safe and economical (uses a standard 9 V battery)
• Seamless connection with personal computer for data transfer (stores 999 data values)
• Modular and interchangeable 4-electrode probes, patented non-polarizing electrodes, and detachable measuring unit
• Versatile (the same unit can be used in field mapping and laboratory experiments)
• Affordable (enquire about our very competitive prices and available discounts)
