FIELD: machine building.
SUBSTANCE: pocket hardness gauge consists of hollow case and of striker with indenter freely travelling in cavity of case. The case and the striker have cross coaxial orifices wherein there are inserted cut-off rods facilitating equality between force effecting the indenter and force cutting the said rods.
EFFECT: pocket gauge for approximate off-laboratory determination of hardness by impact method effecting indenter; effecting force can be specified stepwise within wide range including force applied in traditional methods.
