PARTIAL LIST OF OUR PRODUCTS

1. SuperSting R8 Resistivity and IP Meter
The SuperSting R8 IP is a state-of-the-art 8-channel portable memory earth resistivity meter with memory storage of readings and user defined measurement cycles. It provides the highest accuracy and lowest noise levels in the industry. This new instrument revolutionizes the field of resistivity imaging surveys by its capability to simultaneously measure up to 8 channels using a high power transmitter so that field data collection can reach previously unheard speeds. With the high power transmitter good data can be recorded in difficult locations where time-consuming stacking was the only alternative before.

SuperSting R8 IP can be used with our patented Multi-channel Swift Dual Mode Automatic Multi-electrode cable (patent 6,404,203) or with different capability switch boxes and passive cables to form a system for measurement anywhere, i.e. on the surface, between boreholes or in lakes, rivers and the sea. With this instrument it is now possible to efficiently record 3D data and use a virtually unlimited quantity of electrodes in a single layout. The electrode address is now a 16 bit number which sets range at about 65000 electrodes! Induced Polarization mode records 6 individual IP chargeability windows. The extraordinary speed of this instrument makes it the ideal instrument to be used whenever resistivity monitoring is needed.

2. SuperSting R1 IP Resistivity and IP Meter
The SuperSting R1 IP is a state-of-the-art single-channel portable memory earth resistivity meter with memory storage of readings and user defined measure cycles. It provides the highest accuracy and lowest noise levels in the industry. This new instrument is based on technology developed for the famous SuperSting R8/IP multi-channel instrument. It pushes the performance levels of single channel systems forward by a large step. With the high power transmitter good data can be recorded in difficult locations where time-consuming stacking was the only alternative before.

SuperSting R1/IP uses the patented Swift Dual Mode Automatic Multi-electrode active cable or switch boxes with passive cables. For users of the discontinued Sting/Swift system wanting to upgrade their instrument (ask us about our instrument trade in program) their cable investment can be reused with this new instrument since the old cables can be used also with SuperSting R1/IP. The controller for the cable is now completely built into the SuperSting R1/IP main instrument so there are no extra boxes to carry and connect in the field. Induced Polarization mode records 6 individual IP chargeability windows.

3. MiniSting Resistivity and IP Meter
The MiniSting is a low cost, single channel, memory earth resistivity and IP instrument mainly designed for manual measurements with four electrodes, but can also be equipped with automatic electrodes. The instrument includes instruction manual, the Administrator utility software, test resistor, data download cable, battery charger, external power cable and spare fuses.

4. SuperSting Swift Dual Mode (US Patent 6,404,203) Electrode Switches
The Swift dual mode electrode switches facilitate automatic induced polarization measurement in a multi-electrode array using stainless steel stakes for current injection and non-polarizable (porous pot) electrodes for the potential measurements. The electrode switch can operate either as a dual mode electrode with separate current injection and potential measurement or in mono mode where both current injection and potential measurement occurs through the stainless steel stake. The electrode switches have been re-designed in order to reduce the size of the electrode switch. On one side of the electrode switch is a miniature banana jack where the non-polarizable electrode is connected when the electrode is used in dual mode. When the banana jack is not in use, it is covered by a plug to prevent dirt and moisture to enter the jack.

5. SuperSting Marine
AGI has developed a marine option of the famous SuperSting R8. The system comprises the SuperSting Marine, the Marine Log Manager software and an electrode towing cable. The SuperSting Marine instrument continuously records and stores data from a GPS receiver. Current is injected every 3 seconds and 8 apparent resistivity values representing 8 depth levels are read for each current injection. Our modeling software EarthImager 2D has a Continuous Resistivity Profiler (CRP) option to process the marine data.

6. Graphite Electrodes (US Patent 6,674,286)
Our graphite electrodes are ideal for long-term monitoring of remediation processes or for measurements in water. Due to electrolysis, metal electrodes even stainless steel electrodes, corrode quickly when used as current electrodes. Graphite is not affected by electrolysis and is therefore ideal to be used as current electrodes with our SuperSting Marine System.

7. EarthImager 2D
AGI EarthImager 2D is a Windows 32-bit platform based computer program that interprets two-dimensional (2D) electrical resistivity and induced polarization (IP) data and produces inverted resistivity and IP sections that reveals the sought-after target and subsurface geology. EarthImager turns the complicated resistivity data inversion into a simple two-step process and it takes only a few clicks to get inversion results, i.e., reading a data file and running the inversion. EarthImager also presents a long list of options for advanced users to use.

EarthImager supports all Windows true type fonts and Windows 24-bit true color. Hardware accelerated graphics powered by OpenGL leads to fast graphics rendering. Browsing processing results from one parameter to another and from one iteration to another is a pleasant experience with EarthImager.

8. EarthImager 3D
AGI is proud to introduce the EarthImager 3D resistivity and IP inversion software (IP data inversion is coming soon). This software inverts resistivity and IP data acquired with electrodes arranged in boreholes and/or on the surface and presents a 3D volume of inverted resistivity data with advanced volume rendering technique. The final resistivity or IP image-volume can be rotated in any orientation, zoomed in and out, and translated to anywhere inside the image window in order to see the volume of interest in detail. Colors representing areas of less interest can be made transparent so that the shape of a pollution plume, for example, can be visible. With EarthImager, 3D resistivity inversion can be as easy as two steps: Read Data and Start Inversion with only a few mouse clicks.

Some of the features of the EarthImager 3D are:

• Fast hardware-accelerated 3D graphics powered by OpenGL.
