Auto Surface/Interface Tension Meter

Description:
SIT series automatic liquid surface interfacial tension meter is laboratory measuring instruments using physical methods instead of chemical to measuring surface interfacial tension of liquid, it can quickly and accurately test surface tension value between liquid & gas and interface tension value between liquid. It is widely used in petroleum, chemical, pharmaceutical, printing, textile, electric power industries.
SIT series of automatic surface/ interfacial tension meter, using advanced electromagnetic force closed-loop force measuring system, microprocessor control which can be automatic measurement and easy operation, with high performance, precision test results, stability, repeatability and linearity.

Features:

1. Fully automated measurement, to minimize operation error;
2. Surface tension balance automatically read;
3. One key cleared (any value between 0-400mN), absolutely correct;
4. One key calibration, with standard weights supplied, accurately and rapidly;
5. Using platinum plate method, full compliance with Wilhelmy platinum plate basic principles, so as to achieve:
6. Changes in surface tension values ​​at different times because of the presence of a surfactant produced
7. Measure high viscosity liquids (automatically read the balance)
8. Measure interface tension between different liquid which does not dissolve, such as oil and water.
9. Simple operation, without any external computer control;
10. Sample thermostatic temperature cup, sample temperature detector and external bath.
11. Surface / interfacial tension meter patent number: 200520039453.1.
12. Surface / interfacial tension meter test mode: platinum plate method (or platinum ring)
13. Surface / interfacial tension meter operation: automated sample lift, automatic measurement
