SKC BestChek石棉采樣器

僅來自于SKC---在計(jì)數(shù)、清潔、導(dǎo)電性、收集區(qū)和建造方面（石棉盒是5℃），濾匣可以滿足NIOSH、OSHA和ASTM標(biāo)準(zhǔn)。

計(jì)數(shù)：OSHA方法ID-160要求，每100個(gè)區(qū)域允許有少于4個(gè)纖維，NISOH7400要求每100個(gè)區(qū)域有少于5個(gè)纖維能平均纖維本底。

清潔：OSHA ID-160和NIOSH7400要求在樣品制備期間，清潔過濾器材料，以便樣品具有均勻（非顆粒）本底。進(jìn)行精確分析。這兩種方法規(guī)定了相襯顯微鏡（PCM）分析 SKC BestChek過濾器材料經(jīng)*清潔，以滿足方法的規(guī)范，并適合進(jìn)行PCM分析。

導(dǎo)電性：OSHA ID-160和NIOSH 7400要求使用導(dǎo)電性的濾料夾材料。導(dǎo)電性是包含在濾料材料中的炭黑數(shù)量的函數(shù)。ASTM標(biāo)準(zhǔn)測(cè)試方法和ASTM D257用于確定炭黑含量和測(cè)定導(dǎo)電性材料的方法。SKC Best Chek濾匣塑料包括超過18%的炭黑，用于使用ASTM方法測(cè)試的正確導(dǎo)電性。

收集區(qū)域：OSHA ID-160和NIOSH 7400中規(guī)定了385mm的相容的有效收集區(qū)域。

建造：OSHA和NIOSH建議使用無(wú)泄漏濾料夾，以便進(jìn)行精確的空氣采樣
