冠亞水分活度儀應用行業:《冠亞牌》水分活度儀已被企業、大專院校、科研機構等行業廣泛應用于各種生產與實驗過程中：如醫藥、食品（食品添加劑、脫水蔬菜、肉制品加工、面條、面粉、風干牛肉、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，安裝并連接打印機及測量傳感器。打開電源開關。

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，合上測量傳感器上蓋

③按動儀器屏幕上Nacl鍵，點擊測量時間鍵，根據樣品要求設置好時間

④校準開始，測量結束后。儀器自動報警，左上角燈亮起。記錄校準值。取出樣品皿。

★測量步驟：

⑤按單通道鍵，進入測試頁面

⑥將待測樣品，進行處理粉碎。取一干凈的樣品皿，放入待測樣品。將樣品皿放入腔體內，合上測量傳感器上蓋

⑦按動測量時間鍵，根據樣品要求設置好時間

⑧測量開始記錄數值。此時可以點擊曲線鍵，可實時觀察測量曲線。

⑨測量結束儀器自動報警，左上角燈亮起。按打印鍵,打印并記錄結果

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.
