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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eShore D scale calibration set covering 20 HD to 80 HRB mild hardness range\u003c\/li\u003e\n\u003cli\u003eThree-piece block set for multi-point verification across the stated range\u003c\/li\u003e\n\u003cli\u003eSpecified for use with the Mitutoyo Hardmatic HH-300 hardness tester\u003c\/li\u003e\n\u003cli\u003eHardness Range Description: Mild, suitable for mid-range Shore D applications\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 41114600 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSpecified for use with the Mitutoyo Hardmatic HH-300 hardness testing instrument.
