Duke粒子計數器標準3K,4K系列
Duke粒子計數器標準3K,4K系列
l 使用NIST可溯源尺寸標準
l 廣泛用于潔凈室和其他污染檢測
l 背景干擾程度低
本產品是單分散聚苯乙烯微球（PSL）懸浮液，用于氣態或液體粒子分散系統。
產品采用15ml滴瓶包裝，每一個包裝包括一個標定證明和國家標準技術院(NIST)的可溯源檢測證明
與3000和4000系列產品尺度標準微粒相比，本系列產品是通過對這些尺度標準的精密稀釋而得到的同時具有準確粒徑和粒子計數的產品。每個產品的離子濃度都優化至適于直接用于標定粒子計數儀的濃度范圍， 為用戶省卻了即耗時又容易出錯的濃度調節步驟。
微粒分散介質具有超低的粒子以外的殘留物質，以減少背景干擾。
