DD-300 Digital Precision Durometer with timer function

Made in GermanyOur new DD-300 Durometer range takes rubber / plastic hardness testing to the next level.

The DD-300 hardness tester has been designed to have almost no internal friction and therefore meets the highest quality standards.
The internal movement is guided by ball bearings and makes this durometer one of the best digital durometers available today.
In addition to this the durometer has an integrated timer function that enables to automatically take measurements after a preset time.
This requirement is a part of most standards and enables you to make your measurements even more repeatable.

The DD-300 Durometer is available in the following models: 

  • Shore A 
  • Shore B
  • Shore C 
  • Shore D 
  • Shore O
  • Shore OO
  • Shore DO
  • Asker C

  • Timer function to take measurement after (0-15) seconds.
  • Measuring modes:
    • Continuous Mode
    • Peak Mode
    • Timer Mode
  • No internal friction due to precision engineered bearing system for internally moving parts.
  • Conform to DIN 53505, ISO 868, ISO 7619 and ASTM D 2240
  • Highly accurate and repetitive

Conformance to International Standards
Model ASTM D2240 DIN 53505 ISO 868 ISO 7619
