What do you measure? Who is recommended?
Bearing capacity Evd (MPa) with load p = 0,1Mpa under plate. Big Plate D = 300mm plate, load capacity wired equipment. TP BFStB P8.3, RVS 08.03.04, ASTM E2835-11, ČS73 6192, UNE 103807, ROAD 2-2.119, C120 Bearing capacity only, conversion to E2v is required. Measurement range Evd = 5-125 Mpa. It does not measure compactness rate.
