您好, 歡迎來到化工儀器網(wǎng)
水分活度儀的使用方法
冠亞水分活度儀應(yīng)用行業(yè):《冠亞牌》水分活度儀已被企業(yè)、大專院校、科研機(jī)構(gòu)等行業(yè)廣泛應(yīng)用于各種生產(chǎn)與實(shí)驗(yàn)過程中：如醫(yī)藥、食品（食品添加劑、脫水蔬菜、肉制品加工、面條、面粉、風(fēng)干牛肉、干果等）、烘焙食品(面包、蛋糕、餅干、綠豆餅、月餅、饃片等)、飼料、茶葉(綠茶、紅茶)等
水分活度儀怎么用，操作步驟;
①從包裝箱中取出GYW水分活度儀，安裝并連接打印機(jī)及測量傳感器。打開電源開關(guān)。
②取一干凈樣品皿，放入配制好的飽和Nacl溶液。放入儀器測量腔體內(nèi)，合上測量傳感器上蓋
③按動(dòng)儀器屏幕上Nacl鍵，點(diǎn)擊測量時(shí)間鍵，根據(jù)樣品要求設(shè)置好時(shí)間
④校準(zhǔn)開始，測量結(jié)束后。儀器自動(dòng)報(bào)警，左上角燈亮起。記錄校準(zhǔn)值。取出樣品皿。
★測量步驟：
⑤按單通道鍵，進(jìn)入測試頁面
⑥將待測樣品，進(jìn)行處理粉碎。取一干凈的樣品皿，放入待測樣品。將樣品皿放入腔體內(nèi)，合上測量傳感器上蓋
⑦按動(dòng)測量時(shí)間鍵，根據(jù)樣品要求設(shè)置好時(shí)間
⑧測量開始記錄數(shù)值。此時(shí)可以點(diǎn)擊曲線鍵，可實(shí)時(shí)觀察測量曲線。
⑨測量結(jié)束儀器自動(dòng)報(bào)警，左上角燈亮起。按打印鍵,打印并記錄結(jié)果
Definition of food water activity:
Water Activity, Water Activity, or aw) main reaction food equilibrium the amount of free Water, the stability of the reaction of food and the possibility of microbial breeding, and can cause food quality change in the chemical, enzymatic and physical change, often used to measure the ability to endure dry degree. By measuring the water activity of food, choosing reasonable packaging and storage methods can reduce the use of preservative, and can judge the shelf life of food, grain and fruits and vegetables.
