HRS-150型數顯洛氏硬度計以新穎的外觀，直觀的數字顯示裝置和單片機控制系統，使洛氏硬度測試實現了數字化的操作。本機內置打印機，記錄整個測試過程中的主要技術數據。除試臺手動升降外，實現了試驗力的施加、卸除、硬度值直接顯示等自動化運作，本機測試精度高，消除了人為操作誤差，是一臺機電一體化高科技的硬度測試儀器。
    該硬度計適用于黑色金屬、有色金屬和非金屬材料硬度測定。         

    HRS-150 type number shows the rockwell surname degree of hardness account with the novel external appearance,keeping the arithmetic figure of the view the mainfestation equip to control   the system with single a machine,making rockwell surname degree of hardness the test realizes the operation that arithmetic figure turn.The function's proceeding every kind of degree of hardness parameter converts automatically mutually,distcriminating to try an environment for the minimum thickness experiments with the measurement temperature.The inside places the printer,reading related experimenting the result.Realizes the automation operates,dissolving the factitiousness operate with read the few error margin.
    That degress of hardness accounts to be applicable to the black metals and have the color metals with the degree of hardness measurement of the nonmental material.
