落球粘度计功能特点

准确测量透明牛顿流体和气体粘度
● 用途：可准确测量透明牛顿流体和气体的粘度，可作为参照仪器使用。在循环器准确温度控制系统下，其测量精度在所有粘度计中
● 测量原理：在一个倾斜的柱状测量管中对球在试样液体内的滚动进行计时。试样的粘度与小球穿过某一限定距离的时间相关。将测量管翻转可再进行一次测量
● 测试结果：以国标标准中规定的动力粘度的单位mPas 给出

落球粘度计适用行业

Main Features
> High accuracy through improved visibility of falling ball.
> Minimized test time due to accurate return run of the ball.
> Reduced cost of ownership through increased life time of falling tube.
> Extended re-calibration periods through improved bearing support.
The Viscoball viscometer is mainly used for low viscosity substances
such as used in:
> Mineral oil industry (oils, liquid hydrocarbons, ...).
> Food industry (sugar solution, beer, milk, gelatine, fruit juice, ...).
> Chemical industry (polymer solutions, solvents, resin solutions, latex dispersions,
adhesive solutions, ...).
> Cosmetic/Pharmaceutical industry (raw materials, glycerine, emulsions, suspensions,
solutions, extracts, ...).
> Petroleum industry (light crude, machine oil, crude petroleum,…).
> Fuels (petrol, diesel oil, paraffin, …).
> Paper industry (emulsions, pigment dispersion, paper additives, …).
> Paints and varnishes (printing inks, varnishes, water lacquers, inks,…).
> Detergents (liquid washing agents, washing-up liquids, tenside solutions,…).
Measuring principle
The rolling and sliding movements of a ball through the sample liquid are timed in an
inclined cylindrical measuring tube. The sample viscosity is correlated to the time the
ball requires to traverse a definite distance. By turning the measuring tube upside down
again the return of the ball may also be used for an additional measurement applying
the return constant. The test results are given as dynamic viscosity in the internationally
standardized, absolute units of mPa·s.
