Automatic Interfacial Tension Tester

Automatic Interfacial Tension Tester

This instrument is designed with ISO 6295, ISO 1409, ASTMD1417, EN14370 etc“Test Methods for Interfacial Tension of Petroleum Products between Oils and Water (Ring Methods)”. It is suitable to determine interfacial tension between mineral oils and water under non-equilibrium conditions (Liquid-liquid interface). It can also be used to determine surface tension of various liquids (liquid-gas interface). 

 

Features
 With a advanced electromagnetic balanced force sensor, operator can get high precise and reproducible testing results.

 Big 5touch screen can show the current environment temperature, current tension, peak tension, the equivalent tension etc, easy to operate.

 Built in two testing methods---platinum ring and platinum plate, operator can choose anyone or both

 Full automatic operation can eliminate all human error. Platinum plate can lock liquid interface automatically, platinum ring shows tension curve, 

and peak tension will be locked automatically, without any conversion, the screen tension will shows the values directly.

 Calibrate automatically in full range: weights weight, pure water tension and ethanol tension

 With an elaborate ball screw, the lift system don't have any noise, and its rising & falling speed can be adjusted. 

 The lifting bracket is designed to install and disassemble platinum ring and platinum plate easily.  Operator can calibrate force value anytime by standard weight 

 Peeling function by one button, no drift for zero point and no beat for showing data

 Automatic compensation for environment temperature: taking the water and ethanol as standard , the tester converts automatically the 

sample's tension value under 20

 Data collection software for optional
