Asker® Instruments
The Asker® Durometer Type B employs the same indentor as a Type D while incorporating the spring force of the Type A, therefore suited for measuring materials harder than may be accurately measured by a Type A. It is useful for the hardness determination of materials such as unglazed pottery clay, semi-rigid rubber and green ceramics.
