The digital viscometer is suitable for measuring the absolute viscosity and rheological properties of various liquids and semifluids. Compared with similar instruments, the instrument has high measurement sensitivity, good anti-interference performance, wide working voltage (110V-220V, 50HZ-60HZ can be) reliable test results, easy operation, elegant appearance and other characteristics. It is widely used to measure the viscosity of various liquids such as oils, coatings, plastics, foods, medicines, adhesives, etc. It has been widely used in scientific research in petrochemicals, medicine, food, light industry, and textiles. Digital viscometer is one of the most used precision instruments in new product development and product quality control test analysis.
