Shore durometer

Presses a spring-loaded indentor into rubber or plastic and reads how far it goes in on a 0–100 scale. Shore A is used for soft rubbers and elastomers; Shore D for hard rubbers and rigid plastics.

  • Clean the indentor and foot
  • Inspect the indentor tip for damage

Monthly

  • Check the operating stand's descent speed and level
  • Check reference blocks are within their validity

Annual

  • Full calibration of indentor extension, indentor geometry and spring force at several scale points by an accredited lab
  • Replace worn indentors or springs
SAFETY

Safety precautions

Before you work on the Durometer
  • The indentor is sharp, especially on Shore D. Keep fingers clear and fit the protective cap after use.
  • Handle heavy masses on the operating stand carefully.
In LimsPulse · Calibration Management

Keep every Durometer in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
