盐水的密度，作为比重，可以用比重计或安东帕尔等设计的密度计来测量。结果测量值（通常是比重，但一些比重计测量波美度）将与水中总溶解盐的质量直接相关。如果水中存在大量极细的悬浮颗粒，则该方法可能会失效 - 它们将包含在密度测量中。在野外，可以通过仅测量清水样品、将样品放入高筒中沉降或过滤样品来避免这种情况。虽然这种方法提供了有关溶解盐质量的信息，但它没有提供有关盐的成分或电导率的信息。
与大多数其他方法相比，使用比重计具有便宜的优势。比重计由制造商校准，并且由于它们只是加重的玻璃，因此它们清楚地显示出任何校准不足（它们会断裂）。比重计的易碎性可能被认为是野外研究的缺点，但如果它们装在比重计盒中，它们相当坚固。
比重计有几个范围，结果的精度取决于比重计的范围。对于盐湖研究，三套比重计可以方便地涵盖整个比重范围，从淡水（比重 1.000）到普通盐的结晶点（比重 1.218），一直到泻盐的大致沉淀范围（比重 1.300）。
比重计读数需要根据温度进行校正，因为较暖的水会膨胀并变得密度更低。
密度计价格昂贵，但有测量极精细分辨率的版本。这些机器中使用的细玻璃毛细管 U 形管如果暴露在过高的热量下可能会断裂。这种情况可能发生在沙漠条件下在汽车中携带这些物品时。
[需要有人来写这个方法]?
无论比重计是读取波美度、白利糖度、比重还是其他测量值，其使用方法都是相同的。这里的说明适用于比重 (SG) 比重计。如果您使用其他类型的比重计，则可以使用表格将读数转换为 SG 或 TDS (g/L 或 g/kg)。
- 用盐水样品将量筒装满到溢出点
- 将比重计漂浮在盐水样品中
- 读取并记录比重计轴上的密度水平到水位
- 将温度计插入盐水样品中
- 读取并记录样品的温度
- 根据样品的温度添加或减去密度度数（见下面的温度校正）
- 在实验室日记中记录校正后的读数
- 如果比重计要么沉到底部，要么漂浮过高而无法进行读数，则说明您使用的是错误的比重计。选择一个范围不同的比重计。
- 所有比重计读数都必须从读取时的温度校正到比重计的设计温度。大多数比重计在 15.6 oC (60oF) 下校准。一些盐场使用在 20oC 下校准的比重计。校准温度在比重计轴上注明。使用前检查任何比重计！
- 始终记录未校正的读数和温度，以及校正后的读数。如果出现误算，除非原始数据可用，否则无法校正“校正”后的读数！
以下关于温度校正的建议基于 CRC 物理化学手册和 Bonython 为 ICI 进行的研究 (1948)，
1. 对于比重在 SG 1.000 和 SG 1.100 之间的盐水 温度每变化一度对 SG 的影响并不恒定，但非常近似的校正是
对于样品每高于比重计校准温度 5 度，添加 0.001 对于样品每低于比重计校准温度 5 度，减去 0.001 这对于 0oC 到 40oC 之间的温度足够准确，但不应在此温度范围之外使用。一个更准确的公式是
校正（添加到原始比重计读数中）= 原始 SG + (0.00000359 x temp2 + 0.00006971 x temp – 0.00151687)
2. 对于比重在 SG 1.100 和 SG 1.200 之间的盐水 温度每变化一度对 SG 的影响并不恒定，但非常近似的校正是
对于样品每高于比重计校准温度 3 度，添加 0.001 对于样品每低于比重计校准温度 3 度，减去 0.001 这对于 0oC 到 40oC 之间的温度足够准确，但不应在此温度范围之外使用。一个更准确的公式是
校正（添加到原始比重计读数中）= 原始 SG + (0.000012 x temp2 + 0.000016 x temp – 0.00288)
3. 对于比重高于 SG 1.200 的盐水 温度每变化一度对 SG 的影响并不恒定，但非常近似的校正是
对于样品每高于比重计校准温度 2 度，添加 0.001 对于样品每低于比重计校准温度 2 度，减去 0.001 这对于 0oC 到 40oC 之间的温度足够准确，但不应在此温度范围之外使用。一个更准确的公式是
校正（添加到原始比重计读数中）= 原始 SG + (0.000009 x temp2 +0.000235 x temp – 0.005475)
如果您想将温度校正后的 SG 转换为总溶解固体 (TDS g/L)，则可以从 Baseggio 关于海水衍生的超盐水成分的论文 (Baseggio, 1974) 中推导出一个曲线
TDS (g/L) = -91897 SG4 + 403869 SG3 – 663919 SG2 + 485355 SG – 133408
这条曲线在密度介于 SG 1.000 和 SG 1.250 之间的盐水中最准确。对于高于此值的比重读数，这条曲线产生的转换精度较低。
如果您想直接从未校正的比重和温度转换为 TDS (g/L)，下表提供了一个有用的现场转换，范围从淡水到比重 1.050，温度介于 5oC 和 33oC 之间。
