306L and 307L Shore A & Shore D Durometers

306L Type A Durometers

306L Type A
307L Type D Durometers

307L Type D

  • Shore A Durometers measure rubber, elastomers, neoprene, silicone, vinyl, printing rollers, etc.
  • Shore D Durometers measure hard rubber, plastics, epoxies and similar materials.
  • Accuracy of ± 1 point
  • Max reading pointer standard
  • Easy to read 0 to 100 point dial
  • NIST traceable certification available
  • Meets or Exceeds ASTM D2240 Specifications for Type A & D



The dial scale on the shore durometers can easily display shore hardness to 1/2 point readings. A standard Max-hold hand on the hardness scale remains at the peak until reset. These shore hardness durometers come complete with test block and carrying case, and meet or exceed all aspects of ASTM D2240 specifications.

The included test block is made from aircraft grade aluminum and has a steel leaf spring to give a reading within ±1 of its value. This test block gives much more reliable readings than rubber blocks and its readings are unaffected by normal ambient temperature and humidity.

We guarantee the workmanship and materials of these instruments for one year from date of purchase.
