[content] =>秒準（Mayzum）MAY-3001在線液體濃度計
MAY-3001系列在線液體濃度（糖度）監(jiān)控儀，是根據(jù)光折射的原理來檢測液體的濃度值，光在不同濃度的液體中產(chǎn)生的折射率不同，傳感器將接收到的感光信號轉(zhuǎn)換為折射率；通常情況下不同濃度的液體，其折射率與濃度會呈現(xiàn)一定的數(shù)學關(guān)系。
如右圖所示：從LED發(fā)出的光線經(jīng)過光纖從藍寶石棱鏡的一側(cè)進入藍寶石棱鏡，并到達棱鏡與液體物料的接觸面上，根據(jù)接觸面處液體折射率的不同，一部分光被全反射到棱鏡的另一側(cè)，全反射光的位置會因為臨界角改變而改變（臨界角會因為液體折射率不同而不同），CCD用于精確檢測全反射回來的光的位置，而每一個位置對應的折射率。
二、應用范圍：制藥行業(yè)（中藥濃縮液）、食品行業(yè)（果汁、明膠、膠原蛋白肽……）、脫銷行業(yè)（測量氨水濃度）、酒業(yè)（酒精勾兌）、有機和無機化學材料（酸/堿濃度控制）、化工行業(yè)（酸堿鹽的生產(chǎn)，質(zhì)量管控，泄漏檢測，使用鹽水的地下貯罐）：硫酸、鹽酸、硝酸、氯乙酸、氨水、甲醇、乙醇、鹽水、氫氧化鈉、冷凍液、碳酸鈉、甘油、雙氧水、糖水、果汁、釀造、奶油、藥液、生物液體、醇提、丙酮、DMAC、NMP、DMF、果汁、雙氧水、車用尿素、切削液、乳化液、漿料、乙二醇、氨水……等等
