HTCZ-800 Automatic Surface and Interface Tensiometer

The platinum ring method is a traditional testing method with a history of approximately 70 years. It uses a platinum wire with a diameter of 0.37mm to form a ring with a circumference of 60mm. During the test, the platinum ring is first immersed 2-3mm below the liquid surface (or the interface of two immiscible substances), and then slowly lifted upward. A film will form between the ring and the liquid surface. This film exerts a downward pulling force on the platinum ring. The maximum force exerted by the film on the ring during the entire lifting process of the platinum ring is measured, and then converted into the actual surface (interfacial) tension value.

The HTSZ-800 automatic surface and interfacial tension meter accurately measures the surface tension value of liquids based on the [principle of the platinum ring method]. This instrument integrates a number of advanced technologies and is widely used in industries such as chemical engineering, petroleum, electric power, scientific research, and railways.

Main Functions:

1. 8-inch color Chinese-English touch screen display, controlled automatically by a microprocessor, for fully automatic measurement of sample tension values;

2. The surface of the appearance is treated with electrostatic spraying, which is corrosion-resistant and easy to clean;

3. Equipped with 25℃ automatic temperature compensation function, solving the influence of temperature on the measured tension value;

4. The instrument automatically zeros, measures, calculates, prints experimental results, and has a power-off storage function;

5. The lifting platform of the instrument automatically lifts, with stable performance, low noise and good accuracy;

6. The storage capacity of test results is 300 entries, allowing for easy review of historical records at any time;

7. Uses a magnetic tank enclosed sensor and adopts equidistant multi-point calibration to improve the repeatability and reproducibility of measurement results.
