The RX-Asker-jis durometer conforms to Asker / JIS specifications and is available in an analog and digital version.
They are designed to measure the indentation hardness of rubber, plastics and other materials.
Contrary to the Asker Type C and JA the Type F durometer has a larger foot which allows the user to perform measurements directly on the material. Type F is primarily used to check the hardness of polystyrene foam.
All RX-ASKER models are supplied with a NIST traceable calibration certificat.
