This landmapper can be used for all categories of testing in Soil science, Civil engineering, Agriculture, Environmental pollution and Archaeological Studies.

The device measures electrical resistivity or conductivity down to a depth of 30 m.

Allows you not only measure ER and EC using artificially applied electrical current and four-electrode probes, but also study natural electrical fields (IP) in soils and plants with patented non-polarizing electrodes.

With landmappers, you don’t have to break your back collecting soil samples.

Accurate (Automatically adjusts electrical resistivity/conductivity/potential ranges to provide best measurement accuracy >99%)

ER= 0.01-1 106 Ω m

EC= 1 10-6 – 10 S m-1

EP = -1 to +1 V (0.01 mV)

LandMapper® ERM-02

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 you 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

Don’t break your back collecting soil samples. Reduce amount of samples sent for laboratory analysis and save money. And still make detail soil map of your fields, which will be more accurate than conventional soil surveys. Impossible? Not at all with Land-Mapper ERM-02.

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 30 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 and plants 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.

LandMapper® ERM-01

Throw away your augers and soil samplers! Well, not quite. LandMapper ERM-01 is here to help you 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 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 value is read from the digital display. The device measures electrical resistivity 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.

Key Features

Compact and portable design (weights only 250 g without the probe)



Fast (one measurement takes 5 sec.)



Accurate (automatically accounts for spontaneous potential arising from grounding of the electrodes)



Safe and economical (uses a standard 9 V battery)



Seamless connection with personal computer for data transfer (stores 999 data values)



Modular and interchangeable the 4-electrode probes and detachable measuring unit



Versatile (the same unit can be used in field mapping and laboratory experiments)



Affordable (enquire about our very competitive prices and available discounts)




This equipment measures potential difference, which arises between two electrodes (M and N), when electrical current (I) is applied to two other electrodes (A and B) as in well-known in geophysics four-electrode principle. Device than calculates electrical resistivity from the voltage/current measurements and supplied geometrical coefficient. Direct output from the LandMapper ERM-01 is electrical resistivity in Ohm m, which is easily converted into electrical conductivity (S m-1) by data post-processing.



Advanced scientific research supports versatile applicability and usefulness of the equipment. This equipment is a product of 20 years intense research on electrical fields in soils, applications of electrical resistivity measurements in soil science and electrical geophysical data interpretation. So far, more than 10 dissertations and five books were published on the topic in Russia and USA.


Applications of the equipment

Mapping of soil surface electrical resistivity or conductivity, which is shown to be related with soil texture, salinity, stone content, and pollution by oil products, etc.



Measuring electrical resistivity in soil pits to better diagnose genetic horizons.



Possibility to monitor electrical resistivity distribution in soil profiles without excavation to study freezing-melting, drying-wetting, and solute redistribution processes.



Measuring electrical resistivity in soil columns in model experiments to account for spatial variability and to outline solute flow.



Measuring electrical resistivity of liquids, solid, and semisolid media, such as soil samples, pastes, and slurries; wood; food; and others.

I dey Ib o,

abimbawealth:
I think so too, but a lotta things is involved jare

lols, distance abi

abimbawealth:
Yeye boy...howdy

omo am gud o

omo, I think d company s real

please, any news from egbeda? I hope ppl never beat DAT woman.

nawa oooo, I pray for Nigeria

tosynbolade:
My mind is telling me that Ibadan North LG will perform magic today..z

pls I have interest in ds Ib north....lemme know sup as e dey go

Zikkie:
OK...we agreed to meet tomorrow by 9am. But thus one wey dem don't put police already today, I'm sure tomorrow might be worse.

going in mass can't solve anything, d best thing is to report to higher authority. cos doz police r ready to beat anybody n arrest.

Zikkie:
Were u there on Friday?

noooo,

Zikkie:
U can imagine

what will happen now,

just leaving egbeda lg, police on ground to disperse ppl, d woman said she don't need us DAT she has paid doz DAT she need. so others should go home. my question s, where r d odas DAT she paid. Nigeria!!!!!!!

Sylvesteroses:
Pls when wil Geophysics Department release their own admission list..?

its out now, go n check

sleeky8:
I meant 4th to 6th of feb

just thinking its too early since election na 14th

sleeky8:
Na training from 4 to 6th remain

4 to 6 ke

hollar001:
egbeda lg peep, av been to oluwo nla before inec sent a message, av submitted the photocopy of acknowledgement slip and my nysc discharge cert wit copy of i.d card. I think dat is the screening they are talking abt.

beta u go submit again. was deer today

I pray that INEC increases the pay this time cos the exchange rate of one naira to one us dollar isn't same now as it was then in 2011. Though the allowance went a long way for me then as a corper. I now doubt the sustenance possibility cos I don turn from 'copper' to 'gold'. but wetin man go do nah? Btw, any hint about what the pay gonna be like this time cos I no wan work like an elephant then come reap like an ant... Mbanu!

smile, thanks for confirming DAT....ppl were of d opinion DAT d exchange rate go affect ds yr payment to adhoc staffs....but I don't think it should b xo because fg has already approved like #106 billon for inec b4 d crash in naira....
