Georadar

Georadar SIR-3000.

Georadar is a microprocessor geophysical device for making a quick soil profiling. It is the most modern technique to get soil profiles without drilling or excavating. The device makes it possible to see the soil to the depth from 0,5 to 20-30 meters. It is widely used in the geological exploration, for investigating into reinforced concrete constructions, for charting subsurface objects, in environment protection activities, in legal expertise, in preproject research, construction, etc.

The georadar is successfully used to probe:
• rocky bases;
• aquiferous strata;
• sand, clay, peat, frozen ground, etc;
• the thickness of ice and snow;
• subsurface cavities;
• bridges and pavement;
• pipes and cables;
• concrete constructions;
• saline soil;
• bottoms of water bodies.

The core of the system is a new improved powerful digital control unit SIR-3000 – the latest development by the American company Geophysical Survey Systems Inc. (GSSI) - the world leader in georadar manufacture. It is a reliable highly productive single channel radar system ensuring an unsurpassed scanning speed with a minimal noise level. The device is very compact and was developed specifically to be used by one operator.

Peculiarities:
• lasting, light and very compact;
• a high-solution screen easily read even during the day light;
• User connector CompactFlash;
• Embedded battery with a possibility of “hot change”;
• Plugs USB, Ethernet, RS-232 ensure the system flexibility and universality.
