加拿大Real Tech REAL UV254 ANALYZER 實(shí)時(shí)UV254分析儀
參數(shù): UVT, UV254
UV254分析儀
Real Tech的在線UV254/UVT分析儀可快速實(shí)時(shí)測量水或廢水中的有機(jī)物輸出，如UV254（cm-1）或紫外線透射率/UVT（%）。UV254分析儀利用254nm波長的光，因?yàn)榇蠖鄶?shù)有機(jī)化合物，特別是芳香族有機(jī)物，吸收該波長的光。得益于我們創(chuàng)新的Ortho Beam和Split Sense Pro技術(shù)，可以輸出準(zhǔn)確可靠的測量結(jié)果，從而實(shí)現(xiàn)有機(jī)物監(jiān)測的最高可信度。
連續(xù)有機(jī)監(jiān)測可以為許多應(yīng)用帶來重大價(jià)值，包括紫外線消毒性能和效率、混凝劑量優(yōu)化、DBP形成潛力、水源水監(jiān)測等。
