冠亞水分活度儀應(ying)用(yong)行業:《冠亞牌》水分活度儀已被(bei)企業、大(da)專院校、科研機構等(deng)(deng)行業廣泛應(ying)用(yong)于各種生產與實(shi)驗過(guo)程中：如醫藥、食(shi)(shi)品（食(shi)(shi)品添(tian)加劑(ji)、脫水蔬(shu)菜(cai)、肉制品加工、面條、面粉(fen)、風干(gan)牛肉、干(gan)果等(deng)(deng)）、烘焙(bei)食(shi)(shi)品(面包、蛋(dan)糕、餅干(gan)、綠豆餅、月餅、饃片等(deng)(deng))、飼料、茶葉(綠茶、紅茶)等(deng)(deng)

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(da)印(yin)機及(ji)測(ce)量傳感器。打(da)開電源(yuan)開關。

②取一干凈(jing)樣品皿，放入配制好的飽和Nacl溶(rong)液。放入儀器測量腔體內，合(he)上(shang)測量傳感器上(shang)蓋

③按動儀器(qi)屏幕上Nacl鍵，點擊測量時間(jian)鍵，根據(ju)樣品要求設置好時間(jian)

④校準開(kai)始，測量結束后。儀器自動(dong)報警(jing)，左(zuo)上角燈亮起(qi)。記錄校準值。取出(chu)樣品皿。

★測量步驟：

⑤按單通(tong)道鍵，進(jin)入測(ce)試頁面

⑥將待(dai)測樣(yang)品(pin)，進行處(chu)理粉碎。取一干(gan)凈的樣(yang)品(pin)皿(min)，放入待(dai)測樣(yang)品(pin)。將樣(yang)品(pin)皿(min)放入腔體(ti)內，合上(shang)測量(liang)傳感器上(shang)蓋

⑦按動測(ce)量時(shi)間鍵，根據樣(yang)品(pin)要求(qiu)設置好時(shi)間

⑧測量(liang)開始記錄數值。此時可以點擊曲線鍵，可實(shi)時觀察測量(liang)曲線。

⑨測量結束儀器自動報警(jing)，左上角燈亮起。按(an)打印(yin)鍵,打印(yin)并記錄結(jie)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.
