玻璃浮计使用说明 1.浮计使用前必须全部清洗擦干，（用肥皂或酒精擦洗干净） 2.经过清洁处理干净后的浮计，手不能拿在分度的刻线部分，必须用食指和拇指轻轻拿在干管顶端，并注意不能横拿，应垂直拿，以防折断 3.必须把盛液体之用的筒清洗干净，以免影响读数 4.要充分搅拌液体，等气泡消除后再把浮计轻轻漂浮于液体里，使浮计在检测点上、下三个分度内浮动，待有良好之弯月面进读取读数，否则读数不准 5.要看清浮计读数方法，如浮计内的小标志上标明“弯月面上缘读数”外，其他一律用“弯月面下缘读数”。如图。 6.液体温度与浮计标准温度不符时，其读数应予补正 7.如发现分度纸位置移动、玻璃裂痕、表面有污秽物附着而无法去除时，该浮计立即停止使用。 玻璃浮计允许误差 1.浮计的最大允许误差不得大于+/-个分度值。 2.本玻璃计按国家计量局＜jjg86-86标准玻璃浮计和jjg42－87工作玻璃浮计检定规程＞经上海市标准计量局和本厂计量检定出厂，产品附有合格证。 密度计 标准温度20℃ 密度计的使用范围很广，密度大于1000kg/m³的。用于测定各种酸碱、盐类水溶液的密度。例如酸中的硫酸、硝酸、盐酸以及某些无机酸或有机酸等溶液，碱类中的氢氧化钠（烧碱），氢氧化钾等水溶液，盐类中氯化锌，氯化钠等水溶液。 密度小于1000kg/m³的用于测定甲醇乙醇、乙醚等溶液，以及汽油、煤油、植物油、石油醚等液体的密度。
inhaled electro-hydraulic density meter is designed use method
the 2006-10-7 09:56 questioner: desert love the rain | browsing number: 7201 times
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 piding the position paper, glass cracks, the surface has adhered unclean not remove, the float plan to immediately stop to use.
glass float plan allow error
1. the maximum permissible error float plan must not be more than + /-a piding 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.
