確認不同材質的表面硬度，例如：橡膠、熱性塑料等

符合DIN53505、ISO7619、ISO868、ASTMD2240標準

 

「恆定壓力環」提供穩定下壓力，避免不同測試者施力不均的問題

 

 

概述：

• 硬度計的測量原理在於一個已知的彈簧壓力下，測量頭及探針刺被測入被測物體的表面所受到阻力，反映到刺入程度，刺入程度又轉化為硬度計表盤上的刻度，即為硬度計讀數。
• 轉化成的硬度計的讀數用100肖氏計量。
• 因為壓痕的深度最大為2.5mm，所以測量的物體的最小厚度應為6mm。如果測量物體的厚度小於6mm，則需要把測量樣品堆疊起來，厚度達到6mm以上。從測量樣品的邊緣到內部，測量點應該在12mm以上。

Standard Features

• Easy to use
• High repeatability
• Application range 10 - 90 Shore A units
• Certificate of Compliance with the order 2.1 according EN 10204 is included

Operation

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 testmaterial has to have a minimum thickness of 6 mm. If thickness is less stack some samples til you reach the required thickness.
