Duke粒子計(jì)數(shù)器標(biāo)準(zhǔn)3K,4K系列
Duke粒子計(jì)數(shù)器標(biāo)準(zhǔn)3K,4K系列
l 使用NIST*溯源尺寸標(biāo)準(zhǔn)
l 廣泛用于潔凈室和其他污染檢測(cè)
l 背景干擾程度低
本產(chǎn)品是單分散聚苯乙烯微球（PSL）懸浮液，用于氣態(tài)或液體粒子分散系統(tǒng)。
產(chǎn)品采用15ml滴瓶包裝，每一個(gè)包裝包括一個(gè)標(biāo)*證明和國家標(biāo)準(zhǔn)技術(shù)院(NIST)的*溯源檢測(cè)證明
與3000和4000系列產(chǎn)品尺度標(biāo)準(zhǔn)微粒相比，本系列產(chǎn)品是通過對(duì)這些尺度標(biāo)準(zhǔn)的精密稀釋而得到的同時(shí)具有準(zhǔn)確粒徑和粒子計(jì)數(shù)的產(chǎn)品。每個(gè)產(chǎn)品的離子濃度都優(yōu)化至適于直接用于標(biāo)*粒子計(jì)數(shù)儀的濃度范圍， 為用戶省卻了即耗時(shí)又容易出錯(cuò)的濃度調(diào)節(jié)步驟。
微粒分散介質(zhì)具有超低的粒子以外的殘留物質(zhì)，以減少背景干擾。
