The HHDS32 Digital Durometer Software
is state-of-the art and is an
ideal tool for lab use and for
documentation according to ISO 9000.

PTC Metrology is Accredited by A2LA to ISO/IEC 17025 and ANSI/NCSL Z540-1 for durometer calibration. NIST traceable certification is available for any durometer type covered by current ASTM D2440, ASTM F1957, ISO 868, ISO 7619, or DIN 53505 standards. The Calibration Report will include both "as received" and "as left" data on the force curve measurement. Durometer calibration includes: indenter geometry and extension, indicator linearity from 0 to 100, and mainspring force. Other durometer types, custom models, and durometers of any manufacture can also be certified by PTC Metrology.
