Trade name
Controls CBR loading machine with automatic measurement of test results
Technical description

Digital and continuous measurement with penetration monitoring with an accuracy of 0.001 mm. Load measuring range: up to 50 kN.

Conditions for providing infrastructure

The device is only available in the laboratory. Only employees of the Department of Hydrogeology and Engineering Geology of the AGH University of Science and Technology are authorized to provide service. Laboratory works for external entities are carried out on the basis of a formal order (form available at: http://home.agh.edu.pl/~labgg/dokumenty/) after registration at the Administrative Office of the WGGIOŚ. The implementation of the research requires the consent of the Head of LBGiG.
