產(chǎn)品名稱:手持煙塵納米顆粒計(jì)數(shù)器 testo DiSCMini
發(fā)布時(shí)間:2022-06-07
產(chǎn)品型號(hào):testo DiSCMini型
產(chǎn)品特點(diǎn):手持納米顆粒計(jì)數(shù)器 testo DiSCMini檢測每立方厘米內(nèi)10至500納米直徑的顆粒,而模態(tài)值應(yīng)低于位于200納米。每立方厘米粒子濃度介于約 1'000至1'000'000。測量的精度取決于粒徑分布和個(gè)數(shù)濃度的形狀,并與CPC參考值有10-15%的誤差。該器件應(yīng)當(dāng)每年維修和校準(zhǔn)一次。手持煙塵納米顆粒計(jì)數(shù)器 testo DiSCMini
