Automatic interface tension tester

SL-ZL121 Automatic Interface Tension Tester

Applicable to GB/T6541 standard, based on the ring method (platinum ring method), measure the surface tension (liquid gas phase interface) and interfacial tension (liquid-liquid phase interface) of various liquids. This method is widely used due to its advantages of simple operation and high accuracy. Widely used in industries such as electricity, petroleum, chemical, pharmaceutical, etc.

Instrument Features

1The use of * fast response electromagnetic force balance sensor has improved measurement accuracy and linearity.

2Instrument calibration only requires one point calibration, solving the problem of the previous generation of sensors requiring multi-point calibration. Eliminating the need for zero adjustment potentiometers and full-scale potentiometers.

3Real time display of equivalent tension value and current weight (can be used as an electronic balance for weighing).

4Integrated temperature detection circuit, automatic temperature compensation for test results.

5、240×128Dot matrix LCD display screen, no labeled buttons, with screen protection function;

6Historical records with time stamps, stored as much as possible255One.

7Built in high-speed thermal micro printer, with beautiful and fast printing, and offline printing function.

8Equipped with standardsRC232Interface, can be connected to a computer for easy processing of experimental data.
