Berntsen Monument The Bertsen Monument System is the only solution where long term stability is essential and when accuracy cannot be compromised. Berntsen Monument Systems for high order survey stations, bench marks, GPS stations and monitoring points.
Experience and tests in the USA and Canada have shown that if the monuments are installed to manufacturers specifications, only sub-millimetre movements may be expected in X, Y and Z axes over a period of several years.
Protected by an inspection cover, the benchmark will offer you the ultimate in accuracy for years to come.
