Introduction to manual surface tensiometer

The main technical indicators of this table interface tensiometer are still up to the standard of automatic basic model. In addition to the automatic lifting and lowering of the test platform of the instrument (including fast and fine tuning second gear), the testing process is still automatic testing, calculation and display. Under the premise of ensuring technical indicators, it is an economical and practical product.

Product features:

Compared with other surface tensimeters, manual lifting surface tensimeters include but are not limited to the following advantages:

* sensor sensitive response, high precision, liquid crystal display;

* automatic reading of surface tension balance value;

* manual lifting with fast and fine tuning second gear, simple operation, reliable;

* one key clear zero, ** correct;

* one-key correction, with standard weights attached at random, accurate and rapid;

* small error caused by the instrument itself can effectively control various errors in the measurement process;

* use the platinum panel method or the platinum loop method to connect to the computer, and choose the real-time curve software:

It can clearly show the rise or fall curve of tension caused by the presence of surfactant over time.

Can display the curve and time of two different density liquid interface from low to * high tension value, such as oil/water interface tension value.

* sample thermostatic cup can be selected, external thermostatic tank can control the temperature of the measured liquid.

* easy to operate.
