Description
Technical field
The utility model relates to a kind of physics surveying instrument, specifically, relates to a kind of density tester.
Background technology
Density is the quality in matter per unit volume, is one of characteristic of material, and often kind of material has certain density, and the density of different material is generally different.Therefore, we can utilize density to differentiate material, that is: measure the density of test substance, the density of material various in the density recorded and density meter is compared, just can differentiate that object is that what material is made.
In physics teaching or experiment, the conventional density adopting density tester to measure certain liquid or solid.But the defects such as existing density tester ubiquity is expensive, complex operation, measuring accuracy difference.
Utility model content
The purpose of this utility model is, provides a kind of density tester, to solve above-mentioned technical matters.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of density tester, is characterized in that: comprise liquid storing cup, sampling cup, electronic scales and liquid storing cup support; Described electronic scales is provided with LCDs, power switch key and reset key; The top of described electronic scales is fixed with transparent sampling cup bracket, and described sampling cup is seated in sampling cup bracket; Described liquid storing cup is fixed on the top of liquid storing cup support, is positioned at above sampling cup; Center bottom described liquid storing cup is provided with liquid outlet, and liquid outlet is provided with operation valve; The sidewall of described liquid storing cup and sampling cup all indicates volume markings line.
Beneficial effect: compared with prior art, the utility model structure is simple, and cost of manufacture is low, easy to operate, accurately can obtain the density value of test substance, have a good application prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, density tester described in the utility model, comprises liquid storing cup 5, sampling cup 7, electronic scales 1 and liquid storing cup support 2.Described electronic scales 1 is provided with LCDs 10, power switch key 8 and reset key 9; The top of described electronic scales 1 is fixed with transparent sampling cup bracket 3, and described sampling cup 7 is seated in sampling cup bracket 3; Described liquid storing cup 5 is fixed on the top of liquid storing cup support 2, is positioned at above sampling cup 7; Center bottom described liquid storing cup 5 is provided with liquid outlet 6, liquid outlet 6 is provided with operation valve 4; The sidewall of described liquid storing cup 5 and sampling cup 7 all indicates volume markings line.
When using the utility model to measure fluid density, first testing liquid is injected liquid storing cup 5, and sampling cup 7 is put into sampling cup bracket 3, then unlocking electronic scale 1; Then, opening controlling valve 4, makes testing liquid slowly flow in sampling cup 7; In the process of tapping, by the volume markings line operation control valve 4 on liquid storing cup 5 sidewall, control flow rate of liquid, by observing the volume markings line on the sidewall of sampling cup 7, when the liquid volume in sampling cup 7 reaches setting numerical value, closed control valve 4.The LCDs 10 of electronic scales 1, directly read the mass number of liquid in sampling cup 7, then according to density calculation formula, accurate density value can be drawn.
When using the utility model to measure solid matter density, first water is injected liquid storing cup 5, and sampling cup 7 is put into sampling cup bracket 3, then unlocking electronic scale 1; Then, opening controlling valve 4, makes water slowly flow in sampling cup 7; In the process discharged water, by the volume markings line operation control valve 4 on liquid storing cup 5 sidewall, control flow rate of liquid, by observing the volume markings line on the sidewall of sampling cup 7, when the volume of water in sampling cup 7 reaches setting numerical value, closed control valve 4; The mass number of water in sampling cup 7 is directly read the LCDs 10 of electronic scales 1; Then, solid matter to be measured is thrown in sampling cup 7, the water surface raises, by observing the volume markings line change on the sidewall of sampling cup 7, draw the volume of solid matter to be measured, and draw the mass number of solid matter to be measured then according to density calculation formula, accurate density value can be drawn from the several change of improving quality of the LCDs 10 of electronic scales 1.
