Unique compact geophysical devices

Landviser's products include portative devices for measuring electrical properties (electrical resistivity, conductivity, and potential)  in soils, plants and other semisolid and liquid media. This equipment is small, fully computer-integrated, and easy to use. It is very competitively priced and come handy in many environmental and agricultural applications, including mapping of residential and commercial properties, construction sites, farms, and golf courses. We also offer used GPS units and geophysical equipment of other companies out of Landviser's inventory.

We can also help you with geophysical equipment and software distributed by our Partners. We develop and conduct online and in-person training classes for our clients and distributors. Contact us for comprehensive help for your research and surveying needs.

LandMapper ERM-01 - simple handheld resistivity meter

Throw away your augers and soil samplers! Well, not quite... LandMapper® ERM-01 is new non invasive device, which will help you to map land parcels with contrasting soil properties within the fields quickly, non destructivelyand 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-01 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-02 - new handheld EC/ER/SP meter

LandMapper - field EC meter with lab accuracy*3/19/2014 - we are SOLD OUT of LandMapper ERM-02. New stock is expected in April 2014. ERM-01 model is available (4 units) now with discounted price. We would increase price for a new units for both models to reflect increase in COGs.  Please, contact us info@landviser.com or +1-609-412-0555 / 888-306-LAND to discuss suitability of ERM-01 for your applications or to be put on a waiting list for ERM-02. We apologize for inconvinience.

LandMapper ERM-02 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 new deviceyou 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-02 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 15 m, which is set by varying the size of a four-electrode probe.

LandMapper ERM-02 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.
