Abstract
A nonuniform mixture high-precision density determinator relates to a liquid density determinator, consisting of a cylindrical cup (1) and a conical cup (2). The cylindrical cup (1) is arranged on the upper end of the conical cup (2) and the cylindrical cup (1) is communicated with the conical cup (2). The utility model has the advantages of simple structure, reliable precision, low production cost, up to 500ml capacity, precision within the range of plus or minus 0.5ml, large volume, high precision, low cup and good stability. The utility model solves the contradiction between large volume and low precision of ordinary measuring cylinders and ensures the precision of determining the density of the nonuniform mixture.
Description
Technical field: the utility model relates to a kind of surveying instrument of fluid density.
Background technology: density of liquid is normally measured by densitometer at present, but existing densitometer generally can only be measured single-phase liquid or even mixing material, can't measure for the existing surveying instrument of the density of non-homogeneous mixed liquor.And often to measure the density of non-homogeneous mixed liquor in the real work.Measuring at present the method for non-homogeneous mixed liquor density a kind of is to adopt formula to calculate to determine that the method at first will be got each component content, density clear, so this method is very complicated.Another kind is to use the graduated cylinder amount, but in a small amount the representativeness of tube capacity is not strong, and the long-pending precision of a large amount of cylindrical shells is low again, does not have a kind ofly promptly simply to save trouble, and can guarantee the non-homogeneous mixed liquor density of apparatus measures of measuring accuracy again.
Summary of the invention: the utility model is a kind of non-homogeneous mixed liquor high precision gravimetry instrument of development, makes its density that can measure non-homogeneous mixed liquor, and has high measuring accuracy.The utility model is made up of cylindrical cup 1, beaker flask 2; Cylindrical cup 1 is arranged on the upper end of beaker flask 2, and cylindrical cup 1 is connected with beaker flask 2.The utility model is simple in structure, precision is reliable, low cost of manufacture, its capacity can reach more than the 500ml, precision can be accurate to ± 0.5ml in, have that volume is big, precision is high, the cup body is short, the advantage of good stability, solved general graduated cylinder capacity big with precision the contradiction between low, can guarantee the degree of accuracy of non-homogeneous mixing material mensuration density with the utility model.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Embodiment: present embodiment is made up of cylindrical cup 1, beaker flask 2; Cylindrical cup 1 is arranged on the upper end of beaker flask 2, and cylindrical cup 1 is connected with beaker flask 2, is provided with scale mark 1-2 on the external cylindrical surface 1-1 of cylindrical cup 1.
Principle of work: utilize the capacious condition of beaker flask 2,, utilize the little condition of cylindrical cup 1 diameter,, therefore on cylindrical cup 1, be provided with and measure scale mark 1-2 to guarantee high precision to guarantee high capacity.During measurement non-homogeneous mixing material is placed in the utility model.The beaker flask volume is big, holds basic capacity, and the volume of cylindrical cup 1 is little, holds unsteady capacity, and sample size will be a little more than basic capacity, with the accuracy of guaranteeing to measure during mensuration.
Claims (2)
1, non-homogeneous mixed liquor high precision gravimetry instrument, it is made up of cylindrical cup (1), beaker flask (2), it is characterized in that cylindrical cup (1) is arranged on the upper end of beaker flask (2), and cylindrical cup (1) is connected with beaker flask (2).
