Shore Durometer HPSA-R-M

Durometer according to Shore for determining the indentation hardness of cots, pressure rollers, aprons and many other rubber coated rollers, etc. with max. diameter 200 mm
In dependence to Shore A according DIN 53505, ISO 7619/2, ISO 868, ASTM 2240

Durometer with curved working face for accurate measuring

Special Features

  • The spring loaded outer ring assures a constant measuring pressure and eliminates false readings due to difference between operators
  • Working face slightly curved to fit on rollers
working face hardness tester HPSA-R
  • For diameters > 110 mm the standard model HPSA can be used
  • Adjustable min./max. indicator marks to highlight working range of the hardness tester
  • Optionally available: Calibration certificate with calibration report

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 collored marking on the housing. This ensures a constant pressure and prevents measuring errors.
application for hardness tester HPSA-R 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.

Important for Spinning-Cots
The correct Shore hardness of rubber rolls, special cots, is a critical factor to get the desired yarn structure and quality. As cots have abrasion or rubber is aging, the shore hardness should be checked from time to time.
