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.
