Stech make micro hardness tester was developed in response to the need to test specimens that are small thin irregularly configured or could not otherwise be accommodated by typical durometer types this instrument would perform durometer tests on such specimens quickly and easily with both precision &accuracy, The micro hardness testerwas modeled after the familiar ASTM D2240 Type A durometer. It employs a much lighter mainspring and considerably very smaller indentor. The incorporation of a high quality operating stand overcome the element of sensitivity and added considerable flexibility. The total force necessary to attain a full scale reading is approximately 10% of that of a type A durometer. The lower requirement Of force coupled with smaller indentor, allows for the testing of finished products rather than specially prepared test specimen.
