The instrument adopts the modern manufacturing technology, the instrument adopts advanced special CMOS digital camera, high resolution zoom microscope with times background and high brightness LED light source system, match 3 d sample sets, workbench can be up and down, left and right sides, front and rear direction.Realize the trace sample and precision moving up and down, left and right sides.Also has a design workbench, telescopic rod structure can adapt in different user material thickness increasing.Instrument frame can be regulated according to the size of the style right amount, enlarge the using range of the instrument.And software correction function, the test results after several times can be saved in the same report at the same time, can let users better control data of the material.The instrument design beautiful and easy, simple operation, in accordance with user needs.Suitable for all kinds of industry measuring contact Angle of the user.
1, USES the computer multimedia technology, the optical system is combined with CMOS camera, the image of a droplet is clearly displayed on the computer screen, can will be for the use of measurement under the image storage in an instant, avoid liquid evaporation measurement.
2, special manual is tilting platform and the system measurement purposes advance Angle and back Angle.
3, a baseline correction curve, an automatic image analysis
4, static and dynamic contact Angle, the variation of contact Angle, Angle of forward/backward Angle, inclination Angle, roll Angle analysis;
5, a solid surface can estimate: Fowkes one fluid method, Owen, two fluid, Zisman, Acid - Base surface free energy estimates;
6, surface modification, the convex surface, the concave surface, the surface roughness correction;
7, multiple testing methods: hanging drop method, the droplet method
Around 8, the contact Angle value.
9, the database management functions: query, backup, compression, export EXCEL spreadsheet.
10, the prototype: DKD joint development with Germany, the TUV certification, the first domestic configuration standard parts.Including: round (60 °, 90 °, 120 °), elliptic (115 °), low Angle (3 °, 5 °, 8 °)
11, according to international standard design instrument structure (needles: 0.51 mm, liquid injection precision: 0.01 ul)
12, using the United States imported from trace injection pump, liquid injection precision, precision can reach: 0.01 ul, to avoid human error.
