Xiamen Mirror Worm Technology Co., Ltd. has established a research and development and production base in Xiamen, Fujian. The annual production capacity of JXC online viscometers has reached over 1000 units. The vibrating online viscometers are widely used in industries such as petroleum and petrochemical, silicone oil, synthetic resin, polymer materials, food, ink, plastics, oil paint, coatings, optical fibers, latex, solvents, glass, drilling mud, etc. The product has been updated to the third generation, with a simple structure, accurate measurement, no moving parts, no scaling, and easy cleaning. During operation, the probe vibrates at equal frequency power, and the amplitude varies according to the viscosity of the fluid. The processor captures the amplitude change and processes the signal into a recognizable viscosity signal, which is displayed on the screen. The operator can continuously observe the reaction process status.
