Spring Hammers Calibration Device
Spring Impact Hammer Calibration Device of IEC68-2-75
Product details: Model ZLT-CD1
For testing and calibrating spring-operated impact hammer, in accordance with IEC60068-2-75/1997-08 Annex B, Figure B.1 to B.4 with scale for impact energies from 0,2J to 1,2J.
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.
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.
