電液密度計(jì)使用說明
            1.浮計(jì)使用前必須全部清洗擦干，（用肥皂或酒精擦洗干凈）
            2.經(jīng)過清潔處理干凈后的浮計(jì)，手不能拿在分度的刻線部分，必須用食指和拇指輕輕拿在干管頂端，并注意不能橫拿，應(yīng)垂直拿，以防折斷
            3.必須把盛液體之用的筒清洗干凈，以免影響讀數(shù)
            4.要充分?jǐn)嚢枰后w，等氣泡消除后再把浮計(jì)輕輕漂浮于液體里，使浮計(jì)在檢測點(diǎn)上、下三個分度內(nèi)浮動，待有良好之彎月面進(jìn)讀取讀數(shù)，否則讀數(shù)不準(zhǔn)
            5.要看清浮計(jì)讀數(shù)方法，如浮計(jì)內(nèi)的小標(biāo)志上標(biāo)明“彎月面上緣讀數(shù)”外，其他一律用“彎月面下緣讀數(shù)”。如圖。
            6.液體溫度與浮計(jì)標(biāo)準(zhǔn)溫度不符時，其讀數(shù)應(yīng)予補(bǔ)正
            7.如發(fā)現(xiàn)分度紙位置移動、玻璃裂痕、表面有污穢物附著而無法去除時，該浮計(jì)立即停止使用。

            玻璃浮計(jì)允許誤差
            1.浮計(jì)的zui大允許誤差不得大于+/-個分度值。
            2.本玻璃計(jì)按國家*＜JJG86-86標(biāo)準(zhǔn)玻璃浮計(jì)和JJG42－87工作玻璃浮計(jì)檢定規(guī)程＞經(jīng)上海市標(biāo)準(zhǔn)*和本廠計(jì)量檢定出廠，產(chǎn)品附有合格證。

            密度計(jì) 標(biāo)準(zhǔn)溫度20℃
             密度計(jì)的使用范圍很廣，密度大于1000Kg/m³的。用于測定各種酸堿、鹽類水溶液的密度。例如酸中的硫酸、硝酸、鹽酸以及某些無機(jī)酸或有機(jī)酸等溶液，堿類中的*（燒堿），氫氧化鉀等水溶液，鹽類中氯化鋅，氯化鈉等水溶液。
             密度小于1000KG/m³的用于測定甲醇乙醇、乙醚等溶液，以及汽油、煤油、植物油、石油醚等液體的密度。

How to check its acid density?
And the best answer glass float plan instructions
1. Float plan before using all must dry cleaning, （with soap or alcohol swabbed clean）
2. After cleaning clean the project after float, hand can't take the degree of the scribed line, must use forefinger and thumb gently in the top line shall take, and can't take the attention should be vertical take, in case the broken
3. Must be and the use of liquid of tube clean, lest affect reading
4. To fully mixing liquid, and then put the bubble eliminate float plan gently floated in the liquid, make the float in the first project, three points degrees floating, to have good on the curved surface into take a reading, reading or not
5. To see floating plan reading method, such as floating in the small sign plan marked "crescent margin on reading" outside, other all use "crescent inferior to face reading". As shown in figure.
6. The liquid temperature and float plan not standard temperature, the reading should be corrected
7. Such as the discovery of dividing the position paper, glass cracks, the surface has adhered unclean not remove, the float plan to immediay stop to use.

Glass float plan allow error
1. The maximum permissible error float plan must not be more than + /-a dividing value.
2. This glass plan according to the national standard measurement < JJG86-86 standard glass float plan and JJG42-87 work glass float gauge verification procedures > by Shanghai standard standard measurement and our factory metrological verification factory, the product with certificate.

Standard temperature 20 ℃ density meter is designed
The use of density meter is designed range is very wide, density is more than 1000 Kg/m ³. Used for testing all kinds of acid and alkali, salt solution density. For example the sulfuric acid, nitric acid, acid hydrochloric acid and some inorganic acid or organic acid etc solution, alkali in the class of sodium hydroxide （caustic soda）, potassium hydroxide solution etc, salts of zinc, such as sodium chloride solution.
Density of less than 1000 KG/m ³ used for determination of methanol, ethanol, ethyl ether solution, and gasoline, kerosene, vegetable oil and petroleum ether the density of its liquid.
