Omnimark Instrument Mark3模塊化的水份測(cè)定設(shè)備用于樣品量極大的生產(chǎn)檢驗(yàn)。Mark3是根據(jù)失重法(Loss On Drying)的測(cè)試原理。它主要由兩個(gè)模塊組成,加熱和控制模塊。加熱模塊利用紅外線石英管加熱,使樣品均勻地快速受熱??刂颇K更可同時(shí)連接四組加熱模塊,同時(shí)檢定四個(gè)相同或不同樣品,增加檢定效率。每個(gè)模塊可以設(shè)定不同的測(cè)量參數(shù)。在設(shè)置菜單中存儲(chǔ)的表格可以控制哪個(gè)用戶可以使用哪個(gè)模塊,防止從其他人的模塊測(cè)量引起的混淆,確保測(cè)量的可追溯性。 | |
另外,Mark 3特別適合用于塑料行業(yè),它在塑料行業(yè)的優(yōu)勢(shì)(主要與卡氏法水分儀比較): | |
加熱失重法原理,檢測(cè)無(wú)需試劑,無(wú)后期費(fèi)用 | |
檢測(cè)時(shí)無(wú)釋放有毒氣體,更環(huán)保 | |
樣品無(wú)需預(yù)處理,操作簡(jiǎn)便,既能用在實(shí)驗(yàn)室也能用在車間現(xiàn)場(chǎng) | |
標(biāo)準(zhǔn)ASTM6980(該標(biāo)準(zhǔn)專門(mén)針對(duì)塑料水分檢測(cè)的) | |
