| HV-30型維氏硬度計(jì)簡(jiǎn)介 HV-30型維氏硬度計(jì)采用自動(dòng)加卸荷試驗(yàn)力機(jī)構(gòu)，試驗(yàn)力保持時(shí)間可0～30秒任意選擇，通過(guò)軟件線形調(diào)節(jié)改變光源強(qiáng)弱，操作簡(jiǎn)便迅速，測(cè)量時(shí)采用獨(dú)特的測(cè)量轉(zhuǎn)換和測(cè)量微目鏡一次測(cè)量讀數(shù)裝置，使用方便測(cè)量精度高。
該硬度計(jì)應(yīng)用范圍廣，即適用于測(cè)量微小、薄形及表面滲鍍層處理后的零件，也適用于一般機(jī)械零件測(cè)試，是工廠及質(zhì)檢部門(mén)進(jìn)行研究測(cè)試的理想的硬度測(cè)試儀器。
