Product Description
Automatic Surface Tensiometer
SIT100/SIT200 are upgraded with greatly improved performance
* Adopt 4.3-inch touch screen, all operations and information are completed or displayed on the screen;
* The sensor adopts the principle of electromagnetic force balance, with high sensitivity, high precision and high repetition;
* Both platinum plate method and platinum ring method;
* Fully automatic measurement, without calculation, directly display the surface tension value or interfacial tension value;
* One-key reset & correction; digital processing technology, no deviation;
* Users can use standard samples (distilled water and pure ethanol) to calibrate the data to ensure the accuracy of the measurement;
* Display measurement curves in real time, save measurement results, print main parameters, data and curves;
* Double-door transparent plexiglass windshield, easy to operate and reduce the use of environmental requirements;
* Password management function to ensure data traceability and prevent data modification and accidental deletion;
* Chinese/English interchangeable operation
Adopts high-precision electromagnetic sensor
It is specially developed for surface and interfacial tension testing. Although the cost is much higher than that of traditional strain sensors, it has many advantages such as high measurement accuracy, good repeatability, and little influence by temperature. It is the current international mainstream measurement solution.
