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).

MAIN PARAMETERS:

- Frequency range: 2,5-250 kHz
- Operating time with 14 freqs: 2 sec (you can choose any of 14 deferent frequencies)
- Transmitter power: 600 W
- Receiver sensitivity: 1 mV
- Noise floor: 50 nV
- Storage capacity: 8000 search points
- Battery operation time: 12 hours
- Weight: 7 kg
- Length: 2,75 m



Complete set of the NEMFIS equipment:

- transmitter part;
- receiver part;
- PDA with software for control and real-time visualization;
- GPS for tracking in auto scanning mode;
- laptop with software for 3D visualization;
- video courses for study to work with NEMFIS;
- instruction manual;
- transportation bag.


Comparison field works of NEMFIS vs commercial EM devices shows that NEMFIS is essentially advantageous in resolution, noise immunity and sensitivity.
Recently NEMFIS is one of the most cost-effective solution for the upper crust exploration.

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.

Our company FCG “Ecology” was established at 2001 year. We are work in deferent science and social projects. Such as developing, production and supply of measurement, security and geophysical equipment, real-time localizing systems and special software. Our regular customers is a government institutions such as Ministry of Interior of Russian Federation; regional suppliers of potable water to the citizens “Vodokanal”; State atomic energy corporation “ROSATOM” and others. We are always seek for serious two-side effective relationship with our partners and customers.
One of the primary direction of organization activity is development and integration of innovations into different spheres. Our mission is to improve hi-tech sector in Russia. We work with several scientific institutions and research groups, participating in perspective projects.
Company support team contain only high professional engineers and programmers that always improve the functionality of the products after continuously research in geophysics and analyze of customers feedback.
Start from 2008 our company working under the several software projects for automatization of industrial processes. This software contain machine learning algorithms that developed on conception of recursive neuro-system.
From 2009 our company start to produce systems for real-time localizing that can be very useful with geophysical instrument for precise positioning of equipment and real-time associating of current measurement points.

Nemfis

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.
