產(chǎn)品簡介
電動表面洛氏維氏硬度計(jì)是輕載荷洛維二用表面硬度試驗(yàn)機(jī)，該機(jī)具備了六種試驗(yàn)力，能滿足表面洛氏、維氏硬度的測試。試驗(yàn)力的施加、保荷和卸荷自動完成。使用方便，該機(jī)測試靈敏度高。并可按用戶要求，可改裝鋁制品兼用測試布氏硬度。
適用范圍
鋼、表面淬火鋼、銅、鋁合金、薄板、帶鋼、硬質(zhì)合金鋼、鍍鋅、鍍鉻、鍍錫、材料表面熱處理和化學(xué)表面處理的金屬材料。
Motorized Superficial Rockwell & Vickers Hardness Tester with 6 steps testing force is able to meet the needs of superficial Rockwell & Vickers hardness tests. Testing force can be loaded, kept and unloaded automatically. Therefore the tester is easy to use and widely welcomed by many users. (The present instrument can be reformed specially to measure Brinell hardness value for aluminum products according to users special requirement.)
Usage Range:
Steel, surface hardened steel, copper, aluminum alloy thin sheet, hard alloy steel, zinc layers, chrome layers, tin layers, surface heat treating and chemical treating materials, etc.
