【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。 Densitormetersareofverywideapplication.Theyareusedtodeterminethedensityofliquidsheavierthanwater(suchassulfuricacid,nitricacid,hydrochloricacid,certaininorganicacidsandorganicacids)andalsothedensityofliquidslighterthanwater(suchastheaqueoussolutionsofmethanol,ethanolandether).
