- Compact and portable design (weights only 250 g without the probe)
- Fast (one measurement takes 4 sec.)
- Non invasive device (only press firmly into few inches of soil and measure down to 5 meters)
- 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, VES arrays, and detachable measuring unit
- Versatile (the same unit can be used in field mapping and laboratory experiments)
Mapping of land surface electrical resistivity or conductivity, which is shown to be related with soil texture, salinity, stone content, pollution by oil products, etc.
Measuring electrical resistivity in soil pits to better diagnose genetic horizons.
Possibility to monitor electrical resistivity distribution in soil profiles without excavation to study freezing-melting, drying-wetting, and solute redistribution processes.
Measuring electrical resistivity in soil columns in model experiments to account for spatial variability and to outline solute flow.
Measuring electrical resistivity of liquids, solid, and semisolid media, such as soil samples, pastes, and slurries; wood; food; and others.
Throw away your augers and soil samplers! Well, not quite...LandMapper® ERM-03 is new non invasive device, which will help you to map land parcels with contrasting soil properties within the fields quickly, non destructively, and cost-efficiently.
Landmapper is an excellent tool for soil mapping required for environmental consulting, golf courses maintenance, construction services, farm management, new land development, and real-estate planning. It is a must have tool for forensic and archaeological investigators, even for serious treasure hunters. Using this non invasive device prior to soil sampling you can significantly reduce the amount of samples required and precisely design a sampling plan based on the site spatial variability.
LandMapper® ERM-03 measures electrical resistivity or conductivity of soils and related media for express non invasive 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 surface and an electrical resistivity value is read from the digital display. The device measures electrical resistivity in a surface layer of the depth from 2 cm down to 20 m, which is set by varying the size of a four-electrode probe. Measurements are based on well-known four-electrode principle, which allows to avoid influence of electrode contact potential on measured electrical conductivity or resistivity of the media and obtain accurate readings. The field tests were performed by our customers in USA, Russia, China, Canada, Sweden, France, Germany, Iraq, Dubai, Brazil, Panama and many others.
LandMapper ERM-04, equipped with proper non-polarizing electrodes, can be used to measure such “noise” electrical potentials created in soils due to soil-forming process and water/ion movements. The electrical potentials in soils, clays, marls, and other water- saturated and unsaturated sediments can be explained by such phenomena as ionic layers, electro-filtration, pH differences, and electro-osmosis. Another possible environmental and engineering application of self-potential method is to study subsurface water movement. Measurements of electro-filtration potentials or streaming potentials have been used in Russia to detect water leakage spots on the submerged slopes of earth dams (Semenov, 1980). The application of self-potential method to outline water fluxes in shallow subsurface of urban soils is described in (Pozdnyakova et al., 2001). The detail description of self-potential method procedure is provided in this manual. Another important application of LandMapper ERM-04 is measuring electrical potentials between soils and plants. An electrical balance between soil and plants is important for plant health and electrical potential gradient governs water and nutrient uptake by plants.
Monitoring of electrical potentials in plants and soils is a cutting-edge research topic in the leading scientific centers around the world.

LandMapper ERM-04 - new handheld EC/ER/SP meter
LandMapper ERM-04 is a newest device in the product line of Landviser, LLC. This portative device can measure three important electrical properties of solid, semisolid, and liquid media: electrical resistivity (ER), conductivity (EC), and potential (EP). Using the most accurate four-electrode principle LandMapper ERM-02 measures ER or EC to help you to delineate areas with contrasting soil properties within the fields quickly, non-destructively, and cost-efficiently. Using the device prior to soil sampling you can significantly reduce the amount of samples required and precisely design a sampling plan based on the site spatial variability.

LandMapper ERM-04 is the most versatile device in LandMapper series and allows you not only measure ER and EC using artificially applied electrical current and four-electrode probes, but also study natural electrical fields in soils (self-potentials) and plants (bio-potentials) with patented non-polarizing electrodes. Electrical balance between soil and plants is important for plant health and electrical potential gradient governs water and nutrient uptake by plants. Monitoring of electrical potentials in plants and soils is a cutting-edge research topic in the leading scientific centers around the world.
