■ Product overview

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, and it is one of the important indicators of product quality in related industries. The automatic interfacial tension tester produced by our company 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.

■ Features

▲Using the original fast response electromagnetic force balance sensor, which improves the measurement accuracy and linearity.

▲ The instrument calibration requires only one point calibration, which solves the problem of multi-point calibration for previous generation sensors. Eliminates the zero adjustment potentiometer and the full scale potentiometer.

▲ Real-time display of equivalent tension value and current weight (can be used as an electronic balance to weigh).

▲ Integrated temperature detection circuit, automatic temperature compensation for test results.

▲ 240×128 dot matrix LCD display, no logo buttons, with screen protection function.

▲ History record with time stamp, up to 255 records can be stored.

▲ Built-in high-speed thermal micro printer, beautiful and fast printing, with offline printing function.

▲ Equipped with a standard RS232 interface, which can be connected to a computer for easy processing of test data (optional).
