Hardness Tester Calibration
WESTport provides ISO/IEC 17025 accredited calibration for the full range of hardness testers and durometers. As a manufacturer of NIST-traceable hardness test blocks, we calibrate against reference standards we produce in-house — a closed-loop advantage few labs can offer.
