HRMS-45型數顯表面洛氏硬度計，是一種較為，采用大屏幕顯示和操作的數字式顯示硬度值的表面洛氏硬度計。通過大屏幕觸摸操作，可對表面洛氏硬度標尺進行選擇，數字式顯示測試數據，各種硬度值之間的換算。并具有對測試數據儲存、打印輸出、RS-232超級終端設置等功能，本機具有很好的穩定性和直觀性。
適用范圍
表面淬火鋼，材料表面熱處理和化學處理，銅、鋁合金等薄板，鍍鋅、鍍鉻、鍍錫材料，軸承鋼，冷硬鑄件等。
HRMS-45 Digital Superficial Rockwell Hardness Tester adopts novel-designed large LCD screen to display, as well as menu structure. It mainly functions are as follows: 1. Selection of Rockwell hardness scales, 2. Exchange hardness values among hardness scales, 3. Output the results of hardness measurement with printer, 4. RS-232 hyper terminal setting is with good reliability, excellent operation and easy watching.
Usage Range:
Surface hardened steel, surface heat treating and chemical treating materials, copper, aluminum alloy sheet, zinc layers, chrome layers, tin layers, bearing steel, cold and hard casting parts, etc.
