Unique compact geophysical devices

Landmapper hand-held resistivity meter compared with AE-72 (standard)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 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. We sometimes offer used GPS units and geophysical equipment of other companies out of Landviser's inventory. Contact us for comprehensive help for your research and surveying needs.

LandMapper ERM-02 - new handheld EC/ER/SP meter

LandMapper - field EC meter with lab accuracy*We have a new bath of LandMappers ERM-02 in stock! Please, contact us info@landviser.com or +1-609-412-0555 / 888-306-LAND to discuss suitability of ERM-01 or ERM-02 for your applications.  *******

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 20 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. 

Happy New 2017 Year!

 

All of us at Landviser, LLC (USA) and IP GeoPro (Russia) are wishing our friends, collegues, customers and everybody else around the world Happy Holidays and a Great New Year! Looking forward to change, trust and fairness for all in 2017!!! We, as a small geo-consulting company, would continue to do our best in studying our Morther Earth and bringing Joy to the World!

Happy New 2016 Year!

2D Dipole-Dipole Electrical Tomography with LandMapper

Manual measuring of electrical resistivity 2D cross-section is possible with LandMapper with supplied (optional) or made by user cable set.

There are two modifications of 2D cable set offered and tested by Landviser, LLC:

  1. Mobile shallow (~2 m depth) set consisted of two T-style probes (AB and MN dipoles) similar to mapping probes. The dipoles are set at 1 m size with possible separation between dipoles (wire length) no more than 5 meters (n=5).
  2. Stationary set (~ 14 m depth) where electrodes are hammered on the soil surface along the straight line at one meter distance. Electrodes are simple metal spikes/nails and is sourced locally (are NOT provided by Landviser, LLC). We supply wires with banana-plug connections to LandMapper terminals on one end and alligator clips on the other end to connect with electrodes.

Principle of measurements with both sets is the same for both cable sets and is illustrated by figure below. You can also watch instructional videos on our YouTube Channel - LandviserLLC
