Shore Durometer |
Durometer according ISO 7619-1 for determining the Shore surface hardness of foams, steering wheels and inner linings of motor vehicles with hardness < 20 Shore A
 |
 The spring loaded outer ring assures a constant measuring pressure and eliminates false readings due to difference between operators | | Working face 44.5 mm Ø | | Application range < 20 Shore A units |
| | Flat bottom prevent tilting and improves the measuring accuracy | | Adjustable Min./Max. indicator marks to highlight working range of the hardness tester | | High repeatability |
|
For measuring the hardness, the spring-loaded outer ring of the housing is pressed downwards until the edge of the ring meets the colored marking on the housing. This ensures a constant pressure and prevents measuring errors.
General:
The principle used to measure shore hardness is based on measuring the resistance force of the penetration of a pin into the test material under a known spring load. The amount of penetration is converted to hardness reading on a scale with 100 shore units.
As the depth of indentation is max. 2.5 mm the test material has to have a minimum thickness of 6 mm. If thickness is less stack some samples til you reach the required thickness.
