Product Details

Kern Analogue Shore Hardness Tester

A compact hand held durometer with drag indicator. Ideal for internal comparison measurement. Supplied in a wooden carrying case for safe and secure storage.

Typical Application

• Measurement of penetration (Shore)

Feature and Benefits

• Mechanical shore hardness meter
• For internal comparison measurement. Standard calibrations e.g. to DIN 53505 are often not possible because of narrow standard tolerances
• Shore A: Rubber, elastomers, neoprene, silicone, vinyl, soft plastics, felt, leather and similar material
• Shore D: Plastics, Formica, epoxies, plexi glass etc.
• Shore A0: Foam, sponge etc.
• Max Mode: Holds the maximum value in the display
• Point Mode: Shows one instant value
• Can be attached to test stands SAUTER TI-A0 (for Shore A and A0), TI-D. (for Shore D)
• Tester Shore A0

 

Parallels, Surface Finish & Hardness

 

Surface Finish

 

Any machined component has a surface geometry which consists of three basic elements:

 

Form or Curvature - Whether the surface has irregular bumps or dimensional changes
Waviness - Whether the surface has regular repetitive ripples or patterns (e.g. milling patterns)
Roughness - The shapes or irregularities that are smaller than, and form part of the waviness pattern (e.g. material micro-structure)

 

Waviness and roughness are traditionally the most difficult elements to measure when comparing surface finish, however, they have a radical effect on the performance of the finished component. Variations will cause aesthetic appearance changes, component wear variations, oil retention variation etc. Many manufacturers therefore specify a range of roughness values which their components should be manufactured to, often expressed as: Ra, Rq (RMS), RzDIN, Ry, Sm,mm.
