YK-31SA 數字式鹽份計
YK-31SA SALT METER

1.測量鹽分範圍: 0~10.00%
2.精確度:± 0.5%
3.具有自動溫度補償功能
4.讀值鎖定功能
5.Size:200 × 68 × 30mm

海洋平均鹽度：3.3%~3.7%
降雨多或有河流注入之海面會小於0.5%
北大西洋3.55%，南大西洋/南太平洋3.52%
北太平洋3.42%
赤道附近鹽度：4.1%，地中海/紅海鹽度：4.1%

導電度=電阻之倒數(鹽度與溫度的函數)可計算出鹽度
海水的含鹽總量，稱為鹽度（Salinity)
以每一公升(1000g)海水所含鹽量的公克數為單位
鹽度=鹽分%*10，鹽分3.3%=鹽度33
