☆總固體溶解量TDS
( Total Dissolved Solids )
檢驗在水中溶解的各類有機物或無機物的總量
表示1升水中溶有多少毫克溶解性總固體
TDS值越大，水中的雜質越多，水硬度越高
TDS無法測出化學物質、細菌、病毒
TDS測量軟水/硬水之軟硬度

應用例：
‧飲用水質標準測試
‧純水機/RO逆滲透-濾心
逆滲透膜-過濾功能(純水的純度)檢測
‧判斷水族箱內水雜質含量，汙濁度監控
‧灌溉、施肥期、土壤改良、園藝研發
水耕栽培，農業栽培技術
‧水產養殖、海釣場、水族館，水質監控
‧消除水痕，水質控制
‧電解水機，進水TDS值監測

‧1 PPM=百萬分之1
‧環保署飲用水質標準，TDS：250PPM
‧純水具有強大之洗淨力，使用TDS計確認雜質含量
