ENVIRO-SAFE?溫度計 

豪華泡沫內襯儲存盒 

金屬鎮流器 

單獨序列化 

濕度計的類型 

普通型比重計沒有一個內置溫度計，使用單獨的溫度計來測量溫度。 

比重的標準尺度是液體比重計測量，比重是樣品在60°F水的密度，60°F的比值。 

API比重計刻度是美國石油學會（API），礦業美國局和美國國家標準與技術研究院（NIST）的標準刻度石油產品選擇。 

波美比重計用于液體比水重，如糖漿。 

布里糖度比重計所使用在制糖業，刻度的度數等于蔗糖的重量在標準溫度下的百分比。 

鹽比重計是按鹽溶液 %飽和度和%重量來刻度的。 

酒精（Tralle與證明尺度）比重計直接測量乙醇比例從0到100％。酒精的規模表明表示酒精從0到200度的證明。證明兩次酒精的比例在溶液體積的百分比。 

土壤比重計測定懸浮液的比重，從而實現一定的等效粒徑的顆粒的百分比來計算的。 

如何讀取比重計 

1.將樣品倒入一個光滑，清晰的氣缸，充分洗凈樣品的一部分。 

2.確保樣品在測試前充分混合。 

3.浸沒在液體中比重計，略低于自然漂浮位置的點。確保液體比重計和液體處于靜止和無氣泡。 

4.測量樣品的溫度，理想情況下，樣品的溫度應等于液體比重計的溫度標準，一般為60°F。溫度差異是不可避免的，校正表可幫助調整。 

5.把你讀取到的液體表面組成hydrometer.Set由八個濕度計和ENVIRO-SAFE?溫度計，EnviroKleen?認證的環保和功能的液體，無毒，無害，可生物降解的綠色液體，精度相當于水銀溫度計，沒有危害，每個溫度計制造在美國，單獨的序列號和準確度的多語言語句指示，精度追溯至NIST和DKD供給，符合RoHS標準。每個液體比重計校準在三重認可的ISO / IEC17025:2005、A2LA的實驗室，對儀器的校準可溯源至NIST。獨立包裝精度的多語言聲明，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.
