Spring Hammers Calibration Device

The principle of this calibration procedure is to compare the energy provided by a spring hammer, which is difficult to measure directly, to the energy of a pendulum, calculated from its mass and height of fall.

Standard Outfit:

1 Pendulum with rigidly clamped spring at the lower end,

1 frame with bearing for the pendulum,

1 scale plate with drag pointer, scale of anodized alumininum,

2 release bases at the frame,

1 base plate with removable release device.

1 electrical indicator for show the energy of spring hammer.
