HBE-3000A電子布氏硬度記

hbe-3000a電子布氏硬度計
hbe-3000a電子布氏硬度計適用于測定黑色金屬、有色金屬的布氏硬度。本機采用閉環(huán)式傳感器加載、電子控制系統(tǒng)，具備10級的試驗力。本機具有精度高、高重復性和穩(wěn)定性，操作簡便等特點。
適用范圍
布氏硬度采用的試驗力大，壓痕直經(jīng)也大，適合具有大晶粒金屬材料的硬度測試，如: 鑄鐵，有色金屬及合金，各種退火、調(diào)質(zhì)處理后的鋼材，特別是對于較軟的金屬，如純鋁、鉛、錫等。
hbe-3000 electronic brinell hardness tester with 10 steps testing force is able to measure hardness values with each 10 brinell hardness scales. the instrument adopts circuit type sensor added with cool system, thus with high precision, high repetition, and reliability and easy operation.
usage range:.
brinell hardness test which adopts heavy testing force and shows large indentation is apply to measure hardness value for big grain metal materials such as casting parts, nonferrous metals and alloy, various tempered steel, hardening and tempering steel, specially for soft metal such as pure aluminum, lead, tin, etc.
