Shore® Standard Round Style Durometers: Description |
 |
 |
| The Shore® Round Style durometer was introduced in 1944. They have been the most widely used instruments throughout the world for the hardness testing of cellular, soft and hard rubber and plastic materials. They are small enough to be carried in the pocket, yet rugged enough to operate in the most hostile environment. |
| The Shore® Round Style durometer was designed to satisfy industry needs for a durometer with a scale graduated in increments of one rather than the five of the Quadrant Style durometer. |
| Its evolution has produced a most accurate analog durometer. The Round Style durometers may be manually applied, or for better repeatability and accuracy, mounted on a Shore® operating stand. |
| Please refer to the Shore® Durometer Selection Guide for an explanation of Shore® model, type and scale designations, as well to assure the proper selection of the Shore® durometer to suit your specific application. |

 |
The maximum reading indicator design is convenient in applications where the maximum reading obtained may not be easily or immediately observed. It is also useful in eliminating errors caused by focal parallax, even in laboratory situations. |
| The maximum reading indicator follows the indicating pointer and maintains its position after the maximum result is attained until it is reset by the operator. The maximum reading indicator imposes very little resistance and does not appreciably effect the determinations attained. |
| However, the coefficient of drag imposed is such that this option is not available on durometer types having a spring force of 113 grams or less. |
|
|
 |
The tolerance indicator design is ideally suited for applications where the test determinations are within a range of acceptability. |
| The bright red, easily visible, tolerance indicators may be adjusted to the desired high—low range, representing user defined upper and lower control limits. |
| The tolerance indicators improve speed, accuracy, and precision while greatly reduce operator error, especially in high volume testing situations. |
| The tolerance indicators are “passive”, in that they do not contact the indicating hand, and do not influence the durometer operation or test determinations. |

Shore® Constant Load Option |
Shore® Half Inch Foot Option |
 |
 |
| The Constant Load Option incorporates a large two inch square presser foot and a mass which can be detached to accommodate storage and mounting on an operating stand. |
The Half Inch Foot Option employs an extended half inch diameter presser foot to accommodate specimens that may not ordinarily be tested with the standard rectangular presser foot configuration. |
