Abstract

An accurate measurement measuring cylinder comprises a base seat, a measuring cylinder wall, a scale ruler, a Fresnel lens, a fixing device and a crosshair. The accurate measurement measuring cylinder is characterized in that the Fresnel lens can slide up and down on the outside of the measuring cylinder, the crosshair is arranged on the Fresnel lens, a corresponding value on the scale ruler is read through the crosshair being aligned at the concave meniscus of liquid, and the fixing device plays a part in fixation of the Fresnel lens. Due to the fact that the Fresnel lens is a plane magnifying lens, and can be used for amplifying observation of the concave meniscus. Due to the fact that the Fresnel lens is made of plastic, a made-up magnifying lens is prone to being bent, and not prone to being broken. The accurate measurement measuring cylinder is simple in structure, accurate in number reading and low in price.

Description

A kind of accurate measurement graduated cylinder
Technical field
The utility model relates to a kind of graduated cylinder, belongs to the graduated cylinder technical field
Background technology
Graduated cylinder is a kind of instrument of measurement liquid volume commonly used.During reading, the concave meniscus of liquid and realization maintenance level, then, the rule reading on the concave meniscus amount of alignment barrel, and the next bit numerical value of degree of estimating minimum scale.Because eye-observation is unintelligible, the lowest part of concave meniscus is not easy observation, causes stochastic error bigger than normal.
Summary of the invention
Technical problem to be solved in the utility model is to improve the sharpness of observation liquid level, the immediately error that reduces to read.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of accurate measurement graduated cylinder, comprise base, graduated cylinder wall, rule, Fresnel Lenses, stationary installation and crosshair, it is characterized in that: Fresnel Lenses can slide up and down in the graduated cylinder wall outside, crosshair is positioned on the Fresnel Lenses, by crosshair alignment liquid concave meniscus, read the numerical value of crosshair on rule, stationary installation plays the fixedly effect of Fresnel Lenses.Utilize Fresnel Lenses to be because Fresnel Lenses is a kind of plane magnifier, can amplify the observation concave meniscus, because it can adopt plastic material, the magnifier of making is flexible, is difficult for broken.This accurate measuring amount barrel structure is simple, and reading is accurate, and is cheap.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of accurate measurement graduated cylinder comprises base 1, graduated cylinder wall 2, rule 3, Fresnel Lenses 4, stationary installation 5 and crosshair 6.When having liquid to pour measurement into, open stationary installation 5, Fresnel Lenses 4 is slided up and down, sight line keeps and concave meniscus lowest part level, by crosshair 6 alignment concave meniscus, stationary installation 5 is Fresnel Lenses 4 fixedly, reads the scale of crosshair 6 on rule 3.
Fresnel Lenses 4 is a kind of plane magnifieres, can amplify the observation concave meniscus, makes observation more clear.Fixing crosshair reading is not only accurate, and can keep for a long time reading.

Claims (2)
