href="http://www.renoscrapbooking.com/Products-18461090.html">硬度分析儀</a></strong>已廣泛應用于工農業生產、科學試驗和國防建設中，它是研究材料的機械性能、選定加工工藝、保證產品質量的重要手段，準確進行硬度測試，對提高產品質量、降低原材料消耗都起著重要作用。隨著新型材料的不斷出現，<strong>硬度分析儀</strong>越來越成為衡量產品性能質量的*的重要儀器，這就需要研制高精度、率、結構先進、實用方便的新型硬度計。<div>　　</div><p align="center"><img alt="硬度分析儀" width="359" align="middle" height="323" src="http://img49.hbzhan.com/9/20190131/636845271794646371580.png" /><br />（硬度分析儀）</p><div>　　使用硬度分析儀手動探頭測量工件的時候，會產生一些疑惑，測量值的穩定性似乎有點誤差，那么，為什么在使用時會產生疑惑呢？</div><div>　　</div><div>　　一、探頭垂直度?，F所有硬度計在使用時，不論臺式還是便攜式的，都要求測頭垂直加載于工件表面，超聲波硬度計也是不例外的。在使用超聲波硬度計時，探頭需垂直于工件表面。這個垂直并非要求垂直，只需要做到盡量垂直，對測量值的影響可以不計。</div><div>　　</div><div>　　二、探頭下壓程度。超聲波硬度計測量前，壓頭會伸出探頭接觸面一點，在測量時，探頭要下壓，使壓頭退回至接觸面位置，實現加載過程。在此過程中，若下壓力度不夠，壓頭沒有退回到接觸面位置，會導致加載力和儀器中設置的加載力不一致，使得出的結果會有偏差，給用戶造成測值不準。在探頭下壓過程中，要確保探頭下壓到位，以免影響測量結果。</div><div>　　</div><div>　　在使用<strong>硬度分析儀</strong>的時候，可能會出現以上兩種情況的一種或兩種，從而產生測量誤差。只要在使用時注意以上情況的發生，就會避免一些因素產生的誤差，從而得到滿意的結果。</div>
