Product Description Automatic Surface Tension Measurement Tensiometer by Du Nouy Ring MethodIntroduction:The Du nouy ring method is a traditional test method, which takes about 70 years. Using a platinum wire with a diameter of 0.37 mm made into a ring with a circumference of 60 mm. During the test, the platinum ring is immersed in the liquid surface (or two non-mixed interfaces) for 2-3 mm, and then the platinum ring is slowly lifted upward, and a film is formed between the ring and the liquid surface. The membrane has a pull-down force on the platinum ring, measuring the maximum force applied to the ring during the entire platinum ring lift process, and then converting it to a true surface (interface) tension value.The Du nouy ring Tensiometer is based on Platinum Ring Method Principle to achieve accurate measurement of liquid surface tension value. The instrument integrates a number of advanced technologies, widely used in chemical, petroleum, electric power, scientific research, railways and other industries.Main Features:1. Full-automatic measuring the sample tension value using a powerful new generation of microprocessor.2 . 10-inch 65K (resolution 800*600) color touch LCD display, Chinese and English prompt menu operation.3 . The surface of the appearance is treated by electrostatic spray, which is corrosion-resistant and easy to clean.4 . With 25oC automatic temperature compensation function, the effect of temperature on the measured tension value is solved.5 . The instrument automatically zeros, automatically measures, calculates, displays experimental results, and has a power-down storage function.6 . The lifting platform of the instrument is automatically raised and lowered, stable, low noise and accurate.7. The use of a magnetic tank closed sensor with equal-interval multi-point calibration improves the repeatability and reproducibility of measurement results.Reference Standards:1.
