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.

Dr. Larisa Golovko (President of Landviser, LLC) will be presenting "Geophysical Methods of Electrical Resistivity and Self-Potential in Agriculture" in first of 

 

 

Agricultural Geophysics Webinar Series: "Application of Geophysical Methods to Agriculture: Methods Employed"

A live webinar on the application of geophysics to agriculture will be offered on:

Tuesday, February 18, 2014, from 3pm - 4:30pm EST
(2:00 - 3:30 CST, 1:00 - 2:30 MST, 12:00 - 1:30 PST)

This first in a series of agricultural geophysics webinars will focus on the near-surface geophysical methods presently being used for agricultural purposes, which include resistivity, self-potential, electromagnetic induction, ground penetrating radar, dielectric sensors, VIS/NIR/MIR spectrometry, gamma ray spectrometry, mechanical soil compaction sensors, and ion selective potentiometry. Five presenters will provide a short overview of agricultural geophysical methods during the first 30 minutes of the webinar. The last hour of the webinar will be devoted to a panel discussion with the presenters, who will answer questions from the audience.

Happy New Year 2014 from Landviser LLC

Dear visitors, clients, collegues and friends!

Landviser LLC is wishing you Happy, Healthy and Prosperious 2014! Let all your ideas to develop into innovative products and services to create more Joy on our planet Earth and gain yet more understanding about our World. We continue to develop and test our equipment for different environmental applications in collaboration with leading research organizations worldwide. This year we would like to congratulate Department of Soil Physics and Reclamation in Moscow State University (M.V. Lomonosov), Faculty of Soil Science with 70th Anneversary:

 

 

Also, this year we added two innovative geophysical devices to our offerings in collaboration with OOO Electrometry and Gelion holding (Russia):

Electromagnetic multi-frequency profiler AEMP-14

Electrical tomography SibER-48 equipment

Do not hesitate to ask us about applications of geophysics in archaeology, agriculture, and environmental sciences. We are here to "Enlighten Your Research".
