一個可更換電極試片的免校正鹽度計之設計

Design of a Calibration-Free Salinometer with Replaceable Electrode Strips

在系統驗證上，我們採用已知氯離子濃度之標準溶液 (分別為0.1 M、0.01 M、0.001 M氯化鉀溶液)，對於所設計之氯離子濃度感測系統進行測試，將所測試之結果建立出氯離子濃度感測器之校正曲線。根據此系統校正曲線，我們取樣自一般海水、港口海水、魚塭水、灌溉水、工廠水溝水及自來水以進行分析檢測，就可以推算出檢測樣品之氯離子濃度。實驗結果顯示本文所提出之氯離子濃度感測器具有檢測速度快、操作簡便、與高準確度等特點。

 

In this paper, a calibration-free salinometer with replaceable electrode strips is proposed, whose sensor is designed by bipolar screen-printed electrode strips. The proposed salinometer system can be used to detect the salinity of substances containing salt, and it can be applied to the detection of salinity in food and in mariculture sea water for evaluating whether its salinity meets the suitable value.
