Type A and D

Meets or Exceeds ASTM D 2240 Specifications for Type A & D

306L Type A
  • Type A measures rubber, elastomers, neoprene, silicone, vinyl, printing rollers, etc.
  • Type D measures hard rubber, plastics, epoxies and similar materials.
  • Accuracy of ± 1 point
  • Max reading pointer standard
  • Easy to read 0 to 100 point dial

307L Type D
306L Type A   307L Type D

Technical Data
Range (Type A & D): 0 to 100 points
Accuracy: ± 1 point
Weight: 8 oz. (226.8 g)
Shipping Weight: 3 lb. (1.4 kg)
Height: 4 in. (10.16 cm)
Width: 2-1/4 in. (5.71 cm)
Depth: 1-3/4 in. (4.44 cm)
Base: 1 in x 1-1/2 in (2.54 cm x 3.81 cm)

The dial scale can easily be read to 1/2 point readings. A standard Max-hold hand remains at the peak reading until reset. Durometer comes complete with test block and carrying case. These durometers 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 it's 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.
