【产品用途】    密度计的使用非常广泛。重于水的，用以测定各类酸、碱、盐类水溶液的密度，例如酸类的硫酸、硝酸、盐酸和某些无机酸和有机酸等。    轻于水的，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。    对研究室、化验室在测定液体密度时，使用二等标准密度计较为适宜。    Densitormeters are of very wide application. They are used to determine the density of liquids heavier than water (such as sulfuric acid,nitric acid,hydrochloric acid,certain inorganic acids and organic acids) and also the density of liquids lighter than water(such as the aqueous solutions of methanol,ethanol and ether).    They are also employed to determine the density of gasoline,kerosene,vegetable oid and petroleum ether.    The second grade standard densitometers are the most ideal meters for the job --- determining the density of liquids---in the laboratories of scientific research institue.【产品规格】 14支组密度计Set of 14 Densitometers测量范围Range分度Subdivision(0.600~2.000) g/cm30.001 g/cm310.600~0.70061.100~1.200111.600~1.70020.700~0.80071.200~1.300121.700~1.80030.800~0.90081.300~1.400131.800~1.90040.900~1.00091.400~1.500141.900~2.00051.000~1.100101.500~1.60028支组密度计Set of 28 Densitometers测量范围Range分度Subdivision(0.600~2.000) g/cm30.001 g/cm3 0.0005 g/cm310.600~0.65080.950~1.000151.300~1.350221.650~1.70020.650~0.70091.000~1.050161.350~1.400231.700~1.75030.700~0.750101.050~1.100171.400~1.450241.750~1.80040.750~0.800111.100~1.150181.450~1.500251.800~1.85050.800~0.850121.150~1.200191.500~1.550261.850~1.90060.850~0.900131.200~1.250201.550~1.600271.900~1.95070.900~0.950141.250~1.300211.600~1.650281.950~2.000
