Mitutoyo 64AAA590 Hardness Calibration Set Shore D

Product Description

The MITUTOYO 64AAA590 is a three-piece hardness calibration set designed for Shore D scale verification across a mild hardness range of 20 HD to 80 HRB. It is used to verify and maintain the accuracy of durometer and hardness testing instruments in calibration and quality-control environments. The set is specifically listed for use with the Hardmatic HH-300 hardness tester. Calibration technicians, metrology lab personnel, and quality assurance professionals install and use this set during routine instrument verification procedures to ensure readings remain traceable and within accepted tolerance.

This calibration set is suited for applications where Shore D hardness verification is required, covering a mild mid-range span from 20 HD to 80 HRB. It is a direct-use accessory for the Hardmatic HH-300 platform and is appropriate for laboratory, production floor, and field calibration settings where consistent durometer performance must be documented and maintained. The three-block configuration allows coverage across the stated hardness range without requiring additional reference standards for this range.

Key Features

• Shore D scale calibration set covering 20 HD to 80 HRB mild hardness range
• Three-piece block set for multi-point verification across the stated range
• Specified for use with the Mitutoyo Hardmatic HH-300 hardness tester
• Hardness Range Description: Mild, suitable for mid-range Shore D applications
• UNSPSC Code 41114600 for procurement and catalog classification

Compatibility

Specified for use with the Mitutoyo Hardmatic HH-300 hardness testing instrument. Confirm instrument model compatibility before use, as calibration standards are instrument-specific.

Installation Notes

Calibration sets of this type are handled and used by calibration technicians or metrology personnel following the instrument manufacturer's verification procedure. Keep calibration blocks clean and free of debris before each use, as surface contamination will affect reference readings. Store blocks in their protective case when not in use to prevent surface damage. Reference the Hardmatic HH-300 user manual for the specific calibration verification workflow.
