德國HPSAO肖氏硬度計

德國HPSAO肖氏硬度計                                                          

Application: 

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.

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. 

Features: 

• The spring loaded outer ring assures a constant measuring pressure and eliminates false readings due to difference between operators
• Working face 44.5 mm ⌀
• 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

Specifications:

* Spring load of outer ring to create constant pressure
