Microhardness test blocks are used to check the accuracy of micro/ macro indentation testers. WESTport microhardness test blocks are available in a comprehensive range of values and loads. Microhardness test blocks are precision mounted for complete test block stability, ease of testing use and then diamond polished to a mirror finish. WESTports state of the art closed loop load cell instrument used for Vickers and Knoop test block calibration insures that the most stable and accurate test process is performed each and every time.

Macro Vickers blocks are the same dimensions as our Rockwell blocks and provide the maximum test surface available at heavy loads.

Vickers and Knoop micro test blocks are calibrated to meet and exceed American and International standards. All microhardness test blocks are calibrated in our ISO/IEC 17025 accredited metrology laboratory with complete traceability to NIST.

WESTport manufactures and provides the largest stocking inventory of Vickers and Knoop Diamond Indenters for all microhardness testing machines.
