產品說明
產品廣泛應用於食品、化妝品和藥品工業的開 發、質控、生產和儲存、煙草、印刷和造紙、 精細化工等行業的生產和質量控制。符合AOAC, FDA, CNS等多項法規
簡易款LabStart-aw 適用於低到高等水活性 ( aw) 範圍測量(0.03aw-1.00aw),對準確性
和可重複性沒有高要求。
獨立特色:
1. 無需花費大量資金即可分析水活性測量。
2. 測量快速準確,可設2分鐘內穩定取得結果。
3. 設備無需特別維護。
4. 大LCD 顯示,可顯示水活性、溫度及濕度%
5. 內部採用全球唯一的Novasina專利技術,使用電阻式電解傳感器量測。
6. 涵蓋了對準確性(+/-0.03aw)和再現性(+/-0.01aw)的低要求。
7. 可隨時二點確效校正( 0.33aw 與 0.75aw二個標準品) 無需消耗,使用
壽命長達數年。
