2. Instrument Selection 2.1 Schmidt OS-120 models There are two models available. • OS-120PT for testing concrete in the very low compressive strength range. Typically from 1 N/ mm2 to 5.0 N/mm2 ( 145 psi – 725 psi). This makes the instrument very suitable for testing fresh concrete to determine the time for formwork removal. -
