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
Affiliated technical field
The present invention relates to the instrument of the measurement liquid a kind of commonly used in laboratory, especially a kind of graduated cylinder with measurement kerosene quality function.
Background technology
Graduated cylinder is the special measurement instrument of measuring liquid volume.Method commonly used when the laboratory measurement liquid quality is first to measure the volume of testing liquid with graduated cylinder, then obtain the density of this testing liquid by tabling look-up, then calculated the quality of this testing liquid by density formula ρ=m/v.Method records quality thus needs first measurement volumes to calculate again, feels inconvenient.
Summary of the invention
In order to overcome the deficiency that adopts said method, the invention provides a kind of graduated cylinder that can measure liquid quality, its existing traditional graduated cylinder can be measured the function of liquid volume, can directly measure the quality of liquid again simultaneously.
The technical solution adopted for the present invention to solve the technical problems is; On traditional graduated cylinder outer wall according to actual needs, engrave the scale mark of at least a liquid quality and quality numerical value thereof (the present invention is to provide the quality scale line of measuring kerosene and quality numerical value thereof as example), its scale mark and quality numerical value determine by the original volume scale value with treat that the fluid density of mass metering is calculated by ρ=m/v formula.Like this, can be by the direct reading of quality scale line as can be known when measuring certain liquid quality.
The invention has the beneficial effects as follows, when measuring liquid quality by graduated cylinder, can directly be read the quality of liquid in graduated cylinder by the quality scale line.Cost of products is extremely low, and is easy to operate.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the graduated cylinder structural representation of traditional measurement liquid volume.
Fig. 2 is embodiment of the present invention structural representation.
1. graduated cylinder outer walls in figure, 2. volume markings line, 3. volume markings value, 4. volume range maximal value, 5. volume unit, 6. quality scale line, 7. quality scale value, 8. quality range maximal value, 9. mass unit.
Embodiment
The present embodiment is to be to increase the function of measuring the kerosene quality on 0～100ml traditional measurement liquid volume graduated cylinder at range.By figure, first by the maximum range value (4) 100 of volume be 0.8kg/m by the density that density meter checks in kerosene
3, then calculate this graduated cylinder according to density formula ρ=m/v and measure the maximum range value (8) of liquid quality and be 80g, carve quality range maximal value (8) 80 at graduated cylinder outer wall (1) volume range maximal value (4) equal-height position thus.Carve the zero graduation line of quality at the zero graduation line equal-height position of volume markings line (2), and then carve equably scale mark (6) by carrying out 80 deciles between quality maximum range value (8) scale mark and zero graduation line, and the minimum division value of this graduated cylinder measurement liquid quality is 1g as can be known.All scale marks of this graduated cylinder, numeral, unit all can disposablely complete when production.
Claims (2)
1. the graduated cylinder that can directly measure liquid kerosene quality, comprise scale mark (2), numeral (3), the unit (5) of measuring liquid volume and the scale mark (6) of measuring the kerosene quality, digital (7), unit (9), it is characterized in that: increase the scale mark (6) of at least a measurement liquid quality, digital (7), unit (9) on the graduated cylinder of measurement volumes.
2. the graduated cylinder of measurement liquid kerosene quality described according to claim 1 is characterized in that: the scale mark (6), numeral (7), unit (9) of measuring liquid quality with the scale mark (2) of the former measurement liquid volume of graduated cylinder, digital (3), unit (4) with the disposable generation in the production of graduated cylinder of identical method for making.
