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 Year 2015!

Landviser wishes  all our clients, colleagues and friends happy holidays, as well as healthy and prosperous New Year!

Желаем всем нашим друзьям и коллегам веселых праздников, а также счастья, здоровья и успехов в Новом Году!

Getting started with 2D resistivity interpretation using RES2DINV

Presentation, embedded below was developed to bring users up to speed in interpretation of their resistivity data. Class for end users was conducted in Indonesia and included training on field data collection with SibER-48 using ~ 900 m long profile in Wenner-Schlumberger and pole-dipole (remote electrode) 2D tomography. On the second day users received hands-on instructions on data import into RES2DINV software, quality assurance of the data based on visual approach as well as through RMS of the interpretation model. 

General discussion about non-uniquness of the subsurface interpretation modl for 1D, 2D, and 3D representations has followed this class.

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.
