• 1/2" diameter base--available in either ASTM Type A or D
  
• Accuracy of ±1 point
  
• Max reading pointer standard

The instrument uses a dial gauge with a full 360° scale and bold easy to read numbers. The dial scale can easily be read to 1/2 point readings. A standard Max-hold hand remains at the peak reading until reset. Anew barrel design has a textured surface for a more secure grip while making hand held measurements.

Durometer comes complete with a precision aluminum test block and carrying case. The instrument's small 1/2" diameter base allows access to confined, hard to reach areas. These durometers meet or exceed all aspects of ASTM D2240 specifications. Certification traceable to NIST is available for nominal cost.

Measures the hardness of soft materials such as foam rubber, sponge rubber, disposable diapers, jells, doughs, etc. The instrument is based on the force of a variable load over an area of one square centimeter and is simply placed on the material to be checked. The resettable ancillary hand records the peak reading.

The pointer can be observed for material creep over a specified time interval if needed. Several readings should be made and the results averaged. The sample should have an area of at least 1- 1/4" square and be at least 3/4" thick. Thinner materials must be stacked (do not glue) to obtain this thickness.
