湿度计的类型 

普通型比重计没有一个内置温度计，使用单独的温度计来测量温度。 

比重的标准尺度是液体比重计测量，比重是样品在60°F水的密度，60°F的比值。 

API比重计刻度是美国石油学会（API），矿业美国局和美国国家标准与技术研究院（NIST）的标准刻度石油产品选择。 

波美比重计用于液体比水重，如糖浆。 

布里糖度比重计所使用在制糖业，刻度的度数等于蔗糖的重量在标准温度下的百分比。 

盐比重计是按盐溶液 %饱和度和%重量来刻度的。 

酒精（Tralle与证明尺度）比重计直接测量乙醇比例从0到100％。酒精的规模表明表示酒精从0到200度的证明。证明两次酒精的比例在溶液体积的百分比。 

土壤比重计测定悬浮液的比重，从而实现一定的等效粒径的颗粒的百分比来计算的。 

如何读取比重计 

1.将样品倒入一个光滑，清晰的气缸，充分洗净样品的一部分。 

2.确保样品在测试前充分混合。 

3.浸没在液体中比重计，略低于自然漂浮位置的点。确保液体比重计和液体处于静止和无气泡。 

4.测量样品的温度，理想情况下，样品的温度应等于液体比重计的温度标准，一般为60°F。温度差异是不可避免的，校正表可帮助调整。 

5.把你读取到的液体表面组成hydrometer.Set由八个湿度计和ENVIRO-SAFE®温度计，EnviroKleen™认证的环保和功能的液体，无毒，无害，可生物降解的绿色液体，精度相当于水银温度计，没有危害，每个温度计制造在美国，单独的序列号和准确度的多语言语句指示，精度追溯至NIST和DKD供给，符合RoHS标准。每个液体比重计校准在三重认可的ISO / IEC17025:2005、A2LA的实验室，对仪器的校准可溯源至NIST。独立包装精度的多语言声明，表示精度可溯源至NIST。

Types of Hydrometers

Plain Form hydrometers do not have a built-in thermometer; use a separate thermometer to measure the temperature . 

Specific Gravity is the standard scale for what a hydrometer measures. Specific gravity is the ratio of the density of your sample at 60°F to the density of water at 60°F.

Degrees API scale hydrometers are selected by the American Petroleum Institute (API), the United States Bureau of Mines, and the National Institute of Standards and Technology (NIST) as the standard scale for petroleum products.

Degrees Baumé hydrometers are used for liquids heavier than water, such as syrups.

Brix Scale hydrometers are used by the sugar industry. The degrees of the scale are equal to the percentage of sucrose by weight at standard temperatures.

Salt hydrometers are graduated in % saturation or % by weight of salt in solution.

Alcohol (Tralle and Proof Scales) hydrometers measure directly in percentage ethyl alcohol by weight in water from 0 to 100%. The Proof scale indicates the proof of alcohol from 0 to 200 proof. Proof is twice the percentage of alcohol by volume in solution.

Soil hydrometers determine the specific gravity of a suspension, enabling the percentage of particles of a certain equivalent particle diameter to be calculated.

How to Read a Hydrometer
1. Pour your sample into a smooth, clear cylinder or jar that is dry or well rinsed with a portion of the sample.
2. Make sure that your sample is thoroughly mixed before testing.
3. Immerse the hydrometer in the liquid to a point slightly below the place where it naturally floats. Make sure the hydrometer and liquid are at rest and free of air bubbles.
4. Measure the temperature of the sample. Ideally, the sample temperature should be equal to the temperature standard of the hydrometer, generally 60°F. If temperature differences are unavoidable, correction tables can help to adjust readings— call our Application Specialists for information.
5. Take your reading at the point where the surface of the liquid crosses the hydrometer.Set consists of eight hydrometers and an Enviro-Safe® thermometer that is EnviroKleen™ certified environmentally friendly and features liquid that is non-toxic, non-hazardous, biodegradeable green liquid. With accuracy equivalent to mercury thermometers, but without the hazards, each thermometer is manufactured in the USA and supplied with an individual serial number and a multi-language Statement of Accuracy indicating accuracy traceable to NIST and DKD. RoHS compliant. Each hydrometer is calibrated in a triple accredited ISO/IEC 17025:2005, A2LA accredited laboratory against equipment whose calibration is traceable to NIST. Individually packaged with a multi-language Statement of Accuracy indicating accuracy traceable to NIST.
