Automatic Interface Tension Tester For Chemical , Petroleum , Electricity , Railway
Product Overview:
The platinum ring method is a traditional test method, which takes about 70 years. It is made of a platinum wire having a diameter of 0.37 mm and a ring having 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 automatic interface tension measuring instrument is based on the principle of [Platinum Ring Method] to measure the surface tension value of precise liquid. The instrument integrates a number of advanced technologies and is widely used in chemical, petroleum, electric power, scientific research, railway and other industries.
The main function:
1. Fully automatic measurement of sample tension value using a powerful new generation microprocessor;
2 .8 inch 65K (resolution 800*600) color touch LCD display, Chinese and English prompt menu operation;
3 .The appearance surface is treated by electrostatic spray, anti-corrosion and easy to clean;
4 .With 25 °C automatic temperature compensation function, it solves the influence of temperature on the measured tension value;
5. The instrument automatically zeros, automatically measures, calculates, displays the experimental results, and has a power-down storage function;
6 .The instrument lifting platform is automatically raised and lowered, stable, low noise and accurate;
7.Using a magnetic can-closed sensor, using equal-interval multi-point calibration, the repeatability and reproducibility of measurement results are improved;
