Surface tension instrument

The main technical indicators of this table interface tensor instrument still meet the standard of automatic basic type. Except for the test platform of the instrument from automatic lifting to manual lifting (including fast and fine-tuning second gear), the test process is still automatic test, calculation and display.Under the premise of ensuring the technical indicators, it is an economical and practical product.

Product features:

Compared to other surface tensors, manual lifting surface tensors include, but are not limited to, the advantages of:

* The sensor is sensitive, high accuracy, liquid crystal display; automatically read the surface tension balance value;

* Manual lifting with quick and fine-tuning second gear, simple and reliable operation; one key zero, * * correct;

* One-click correction, with the random attached standard weight, accurate and fast;

* The error of the instrument itself is small, more effectively control various errors in the measurement process;

* Connect the platinum plate method or platinum ring method to the computer, with real-time curve software:

The rising or decreasing tension in the presence of surfactant can be clearly displayed.

Curves and time showing two different densities of liquid interface from low to * large tension values, such as oil / water interface tension values.

* The sample constant temperature cup is optional, and the external constant temperature tank can control the temperature of the tested liquid.Easy to operate.
