Embodiment Construction

[0010] In this embodiment, the function of measuring the quality of kerosene is added to the traditional liquid volume measuring cylinder with a measuring range of 0-100ml. According to the figure, the density of kerosene is found to be 0.8kg / m from the maximum range value of the volume (4) 100 and the density table 3 , and then calculated according to the density formula ρ=m / v, the maximum range value (8) of the measuring cylinder for measuring the liquid mass is 80g, and thus the mass range is engraved on the outer wall of the measuring cylinder (1) at the same height as the maximum volume range (4) Max(8)80. Carve out the zero scale line of the mass at the same height as the zero scale line of the volume scale line (2), and then carve out the scale evenly by 80 equal divisions between the scale line of the mass maximum range value (8) and the zero scale line Line (6), and it can be seen that the minimum division value of the measuring cylinder for measuring the liquid qual...

Abstract

The invention relates to a common tool for measuring liquid in a laboratory, in particular to a measuring cylinder with the function of measuring mass of kerosene, and provides a measuring cylinder which can directly measure mass of liquid, has a function of measuring volume of the liquid, just like a traditional measuring cylinder, and can directly measure the mass of the liquid. The adopted technical scheme is that mass scale marks and mass values of at least one liquid (taking the liquid mass scale mark and mass values for measuring kerosene as an example) are marked in an outer wall of a traditional measuring cylinder according to actual needs, and the scale marks and the mass values are determined according to the formula of Rho= m / v; according to the method, during measuring the mass of liquid, the mass of the liquid can be directly read out by the mass scale mark. The mass measuring cylinder has the benefits that when the measuring cylinder is used to measure the mass of the liquid, the mass of the liquid in the measuring cylinder can be directly read out by the mass scale mark; the cost of the measuring cylinder is very low, and the operation is convenient.

Description

Technical field [0001] The invention relates to a tool for measuring liquid commonly used in laboratories, in particular to a measuring cylinder with the function of measuring kerosene quality. Background technique [0002] A graduated cylinder is a special measuring tool for measuring the volume of a liquid. The commonly used method when measuring the quality of a liquid in the laboratory is to first measure the volume of the liquid to be measured with a measuring cylinder, then obtain the density of the liquid to be measured by looking up the table, and then calculate the liquid to be measured by the density formula ρ=m / v the quality of. The quality measured by this method needs to measure the volume first and then calculate, which is inconvenient. Contents of the invention [0003] In order to overcome the disadvantages of the above method, the present invention provides a measuring cylinder capable of measuring liquid mass, which not only has the function of traditio...
