The Asker X-JAL Durometer with "L" Extended Pressor Foot - for Normal rubber & softer plastics is a shore durometer that features portable design, ease of operation, non-destructive measurement and optional peak indicators. Supplied with 3 point NIST traceable calibration cert. The X High Performance Shore Durometer is a precision instrument that has an accuracy of ±.75 point and is available in Type F for soft materials like sponge rubber and urethane foam.
As the hardness tester is pressed against the sample, the material resistance force and indentor spring load balance. The depth of the indentor is measured, which provides a measure of the material's hardness. Values are based upon a 100 point scale (accuracy .75 point). However, as time elapses the indicator will "creep" back so that a reading taken a few seconds after the tester makes contact with the sample will be less than the peak reading.
