SI-LBM15A Hydrophilic Balance (DOS film gauge)

SKU: SI-LBM15A Category:
Hydrophilic balance, also known as film gauge (Spread Oil Measuring Apparatus), because the oil has the nature easily expanded with minelayers on the surface of the aqueous solution , if you know some of the oil film expand the area under  certain membrane pressure to determined oil  amount .It is such kind of precision measuring instruments. After the use of the balance of hydrophilic and oil immiscible hydrophilic properties, by a simple operation will be transferred to the surface the oil film pressure of the aqueous solution, expand the area of the film was measured, whereby the amount of oil adhered to the surface of the measuring object. oil easily expanded on the water with monolayer , the expanded area is proportional to the amount. A necessary condition to expand the area when compared to expand oil density (number of molecules per unit area owned) must be certain that the expanded area of a certain time, a certain area in advance of the film were measured amount of oil, obtained after correlation by measuring other film also expand the area under the density of the oil can be obtained.

Main functions and features
1, The operation and data acquisition is controlled by a PC and pre-MCU ,automation and intelligent , minimize operator error;
2, The key components (including sensors) import, test data accurate and repeatable;
3, Based on the entire Chinese WINDOW Windows operating software, user-friendly interface, graphics can be stored in the print data can be secondary treatment;
4, Tank surface area, high sensitivity, small leakage;
5, Can automatically measure the liquid surface tension.
6, Can draw r-A and π-A curve.
7, The film tension can be set into the lower limit according to r-A and π-A curve, slider repeated compression and expansion barrier film.
8, Can be set to a constant tension, pull the slide barrier in the movement of the film in order to maintain constant tension.
9, Film speed is adjustable.
10, Thoughtful design to ensure that the instrument can be applied to routine testing environment, and common configuration PC to work online, smooth running, small vibration, low noise;
11.Our company has completely independent intellectual property rights for this instrument, guarantee the user repairs, upgrades, service rights, and can customize models according to user needs .
