This method is simple to operate, if the precision of electronic balance is 0.1mg, the volume accuracy that then uses this method to measure little article can reach 0.1mm
3, the corresponding precision of surveying little article density can reach 0.1mg/cm
3, this shows that the measuring accuracy of this method is higher.
The technical scheme of the device of little article volume of measurement of the present invention and density is, it comprises electronic balance, it is characterized in that: the overhung of described electronic balance supporting body has weight not act on electronic balance to measure fine rule on the article supporting body, and the lower end of fine rule is connected with uncovered holder carrier.
Described line can be by other member supports such as supports, its weight does not act on the balance, for easy to use, improve measuring accuracy, electronic balance of the present invention has weight not act on cover body on the supporting body, fixes wiredly on the upper wall of cover body, simplifies the structure like this, can in the process of measuring, avoid the interference of extraneous factor, for example gentle breeze etc. as far as possible.
Described fine rule is not for inhaling liquid in the described container, and diameter can be tried one's best carefully, specifically can adopt the waterline of 1 micron～20 microns of diameters.
The volume of a container that filling among the present invention determined density liquid can be placed in the cover body satisfied, satisfy under other prerequisite of measuring pacing items big as far as possible, like this, after placing article to be measured on the holder carrier, liquid level in the container rises, after line carefully arrived to a certain degree, because the volume of container is bigger, the volume of fine rule draining can be ignored after liquid level rose.
But the side of operating cover body for convenience is provided with the door of folding.Hommization is compared in this design, meets people's operating habit.
