  • Scanner Nemfis

    As you know Scanner Nemfis was manufactured by Russian Science Academy at 2002 years. From that time we have collect big statistic of search work with Nemfis by archeologists, geophysics, engineers and other specialists from different institutes of Russian Science Academy complex and local customers.
    We can say with confidence that scanner Nemfis is the first in the world that can give to operator with such accuracy underground conductivity spread. Operator visualize maps from each 14 freqs in real time. We have made the system that give you 3D graphic of underground 8m layer of conductivity spread, thats very simple to analyze. With this scanner you can easily find following objects: ferrous and non-ferrous metal objects, cavity, ceramic or organic objects, and else. Maximum deep of scanning – 8m. For example object 20х20cm it is possible to find at 3m underground, metal object 100×200cm possible to find at 6,5m underground.
    Every non-professional user can learn to work with scanner and analyze the graphic information in very short time.
    Scanner has unique patent technology of receiving and analyzing electromagnetic waves. This searching device generate electromagnetic waves by 14 different frequencies from 2,5 to 250 kHz.
    Now we are start to export the first non-contact scanners that can receive full and very accuracy 3D information about underground 8m layer of conductivity spread in real-time.
    You can order Ground Scanner Nemfis by contact with us through this form.

        electro-tomograph Scala-48

        NEMFIS is a patented three coils sounding device that includes the transmitter and two receivers. It has special geometry of electromagnetic field and harmonic generating on 14 frequencies within the range from 2,5 to 250 kHz. Receivers cancel primary field in the air – so it is no need to make ground balance with this device. With scanner NEMFIS operator can find: non-ferrous and ferrous metal objects, cavity, ceramic and plastic objects, underground structures, tunnels, water and else that has contrast in conductivity level with the ground.
        It is very simple to work with scanner NEMFIS. You can choose one of three methods of searching:
        - Line;
        - Map;
        - GPS tracking.

        For operative scanning of big open air areas – you can choose “GPS track” mode with automatic generating of impulses. After pressing “Start” button you can start moving with device to scan the searching area. GPS will track your position and you will see drawing of conductivity spreading maps (from one of the freqs.) on your PDA in real-time.
        Scanner NEMFIS is measurement device with because it has very precision dipole sensors.
        Interpretation of final data – very easy to understand. Metal object has small value of conductivity and will show in red color (you can choose any color gamma of conductivity level), other objects: caves, plastic boxes, ceramic, stones has different conductivity and you can always recognize it in ground with constant conductivity.
        For detailed work with data measurements – it is possible to draw 3D of conductivity level distribution in the searching volume of the scan area (10m depth).

            Near-Surface Electro Magnetic Frequency Induction Scanner (NEMFIS)

            Near-Surface Electro Magnetic Frequency Induction Scanner (NEMFIS) was developed in Russian Science Academy by Institute of Geophysics. Non-destructive NEMFIS tool can be used to identify precisely archaeological targets. In fact electromagnetic induction (EMI) method has been used for many years in the exploration for ore bodies (ore bodies contain metal and, therefore, are good electrical conductors), and, more recently, to detect voids but at present NEMFIS tool is widely used for archaeological studies.
            The device applied for many tasks. Unique archaeological targets were found by NEMFIS in Mongolia, Italy and Russia. A lot of lost buried communications and leakages from subsurface pipes were located, ground water contamination and water saturation of soils were explored.

              Near-Surface Electro Magnetic Frequency Induction Scanner (NEMFIS)

              While several archaeological works including Paleolithic, Bronze and Iron ages, antique and medieval targets was discovered. That works was made with complex of geophysical instruments: GPR, Vertical DC sounding and magnetometry together with NEMFIS. In some cases only NEMFIS data shows the buried targets and it was proved immediately by excavation.

                  When I can receive my order?
                  Standard delivery time is 4-6 weeks. If we have devices on stock – delivery time 1 week.


                  How I can study to work with the NEMFIS?
                  Device is simple to use, each of customers can study with english video courses.
                  What is the minimum object that scanner can detect?
                  NEMFIS can detect objects with dimensions start from 15х15cm.


                  How penetrating depth of device change in different ground conditions?
                  If the ground has big conductivity – the penetrating depth smaller then through ground with small conductivity.


                  Is it possible to use NEMFIS for metal discrimination?
                  For this time – NO. But we are working on it right now.
