Manual surface tensiometer introduction


The main technical indicators of the interface tensiometer are still up to the standard of the automatic basic model. Except that the test platform of the instrument is changed from automatic lifting to manual lifting (including fast and fine adjustment of second gear), the test 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 tensioning instruments, manual lifting surface tensioning instruments include but are not limited to the following advantages:


* Sensitive sensor, high precision, LIQUID crystal display;


* Automatically read the balance value of surface tension;


* Manual lifting has fast and fine-tuning second gear, easy to operate and reliable;


* One key to clear, ** correct;


* One-key correction, with the standard weights attached, accurate and fast;


* The error caused by the instrument itself is small, which can control all kinds of errors in the measurement process more effectively;


* Platinum board method or platinum ring method is adopted to connect the computer, and real-time curve software is selected:


It can clearly show the curve of tension rise or fall with time due to the presence of surfactant.


The curve and time of two different densities of liquid interface from low to * large tension values such as oil/water interface tension values can be shown.


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


* Easy to operate.
