Automatic Interfacial Tension Tester

Intermolecular force to form the liquid interfacial tension or surface tension, the size of the tension value to reflect the physical and chemical properties of the liquid and its material composition, is the relevant industry one of the important indicators of product quality inspection. PT-BZL-6 Automatic Tensile Tester is applicable to GB / T6541 standard and measures the surface tension (liquid-vapor interface) and liquid interfacial tension (liquid-liquid interface) of various liquids based on ring method (platinum ring method). This method has the advantages of simple operation and high accuracy and is widely used. Widely used in electric power, petroleum, chemical, pharmaceutical, food, teaching and other industries.

Features

1. Using the original fast response electromagnetic force balance sensor to improve the measurement accuracy and linearity;

2. Calibration of the instrument requires only a little calibration, which solves the problem of multi-point calibration of the previous generation of sensors. Eliminating the need of Zero adjustment potentiometer and full range potentiometer;

3. Real-time display equivalent tension value, the current weight (can be used as electronic balance weighing);

4. Integrated temperature detection circuit, the test results automatically temperature compensation;

5. 240 × 128 LED display, no logo button, with screen saver function;

6. With time stamp history, up to 255 storages

7. Built-in high-speed thermal miniature printer, print beautiful, fast, with offline printing;
