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 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. 

Key Features

It's an awesome piece of writing in support of all the web viewers; they will get advantage from it I am sure.

I have learn several excellent stuff here. Definitely worth bookmarking for revisiting. I wonder how so much effort you set to make this sort of magnificent informative web site.

Basically ERM-01 only

Basically ERM-01 only measures resistivity (can be converted to conductivity afterwards using simple formula EC=1/ER) and ERM-02 can output EC directly in the field and also measure electrical potential (self-potential) with two non-polarizing electrodes. Data from ERM-01 could be stored and downloaded to PC, same for ERM-02, but ERM-02 can be connected to PC and measurements directed by software (GUI is under development, source code for connection protocol is provided to customers).
