Oil Tension Tester

MEZL-W503 Fully Automatic Oil Tension Tester

Intermolecular forces generate interfacial tension or surface tension in liquids. The magnitude of this tension reflects the physicochemical properties and composition of the liquid, serving as a critical indicator for assessing product quality across relevant industries. The fully automatic surface tension tester complies with GB/T 6541 standards and employs the ring method (platinum ring method) to measure the surface tension (liquid-gas interface) and interfacial tension (liquid-liquid interface) of various liquids. This method is widely adopted due to its simplicity and high precision. It finds extensive application in power generation, petroleum, chemical engineering, pharmaceuticals, food processing, and educational sectors.

1) Features an innovative fast-response electromagnetic force balance sensor, enhancing measurement accuracy and linearity;

2) Instrument calibration requires only a single-point calibration, eliminating the multi-point calibration needed in previous sensor generations. Eliminates the need for zero adjustment potentiometers and full-scale adjustment potentiometers;

3) Real-time display of equivalent tension value and current weight (can function as an electronic balance);

4) Internal automatic temperature control maintains the instrument at the national standard temperature of 25°C, ensuring accurate test results;

5) 240×128 dot-matrix LCD display with unlabeled keys and screen saver function;

6) Time-stamped history log stores up to 255 records;

7) Built-in high-speed thermal microprinter delivers neat, fast printing with offline printing capability;

8) Equipped with a standard RS232 interface for computer connectivity, facilitating experimental data processing;

9) Supports fully Chinese/fully English interface display.

The MEZL-W503 Fully Automatic Tension Tester employs the ring method and complies with GB/T 6541 standards. It measures surface tension and interfacial tension of liquids, serving quality control in power generation, petroleum, chemical, pharmaceutical, food, and educational sectors.
