Features
The force between molecules forms the interfacial tension or surface tension of the liquid. The magnitude of the tension value can reflect the physical and chemical properties of the liquid and its material composition. It is one of the important indicators for the quality of products in related industries. This product conforms to the GB/T6541 standard and is based on the ring method (platinum ring method) to measure the surface tension of various liquids (liquid-gas interface) and the interfacial tension of liquids (liquid-liquid interface). This method has the advantages of simple operation and high accuracy and is widely used. It is widely used in electric power, petroleum, chemical, pharmaceutical, food, teaching and other industries.
1. Adopt the original fast response electromagnetic force balance sensor to improve the measurement accuracy and linearity;
2. The instrument only needs to be calibrated at one point, which solves the problem of multi-point calibration for the previous generation of sensors. Eliminates zero-adjust potentiometer and full-scale potentiometer;
3. Real-time display of equivalent tension value and current weight (can be used as an electronic balance for weighing);
4. Integrated temperature detection circuit, automatic temperature compensation for test results;
5.240×128 dot matrix LCD display, no logo button, with screen protection function;
6. History records with time stamp, up to 255 stored;
7. Built-in high-speed thermal micro printer, beautiful and fast printing, with offline printing function;
8. Equipped with a standard RC232 interface, which can be connected to a computer for easy processing of test data (optional);
