 Leading design of weighing sensor

- Electromagnetic force balance sensor technology, expertise in micro-weighing analysis

- Better temperature drifting correction, zero tracking technology

- High data updating speed (23 data/s) and processing with more reliable values.

- World’s first rear sensor (A101, A606), useful for volatile & corrosive sample liquid analysis, e.g. liquid ammonia and acid substances, etc.

- Double-microchip processing technology, with better data-handling capacity and higher speed of processing.

- Upgradeable software, customized to meet your special measurement requirements.

 High-precision sample positioning stage and temperature control system

- Stepper motor controlled high-precision vertical travel positioning stage, with resolution up to 0.1μm and repetitive-positioning accuracy up to 2μm.

- Digital temperature sensor made of semiconductor with temperature resolution of 0.01℃ and absolute temperature accuracy of down to 0.0625℃

- Sample chamber controlled by water circulator offers best temperature control.

Comfortable operation process

- Universal USB2.0 communication port provides stronger compatibility, higher speed, and convenient access to laptops and new-model desktops without RS232 port.

- One-key zeroing and full-auto measurement with simple and convenient operation, to minimize errors caused by human operation.

- Humanizing pre-wetting function, designed for oily sample measurement.

Some samples can’t well wetting Wilhelmy plate or DuNoüy ring for the first time, especially for some oily sample. Our uniquely designed pre-wetting function can provide a more humanized solution for you in these cases.

- Multiple self-calibration functions to enhance measurement reliability

Series A60 are equipped with both weighing sensor calibration and self-calibration function of sensing interface (Wilhelmy plate and DuNoüy ring), which is much better than other manufacturers’. It can enable you to control the reliability of measured value more effectively.

Anti-static design to improve measurement accuracy of surface/interface tension (for optional)

- USA KINO adopts ionic wind technology to avoid detection error of liquid-gas interface caused by electrostatic.

- What is more, ion beam kit module is provided for better anti-static experience. The anti-static device will be always on during measurement. It’s most effective in powder/ fiber measurement to avoid powder electrostatic adsorption and deformation of single fiber.

- Usage of glass door with anti-static coating can effectively isolate conduction of electrostatic.

CAST®1.0-powerful functions and user-friendly interface

- More methods available for you to make a comprehensive solution. USA KINO exclusively provides 3 methods, including classical Wihelmy plate method (slide Wihelmy plate method), modified Wihelmy plate method and DuNoüy ring method.

- USA KINO provides you a series of weight-based wettability analytical methods for solid material, e.g. contact angle analysis by Wilhelmy plate method , fiber contact angle analysis, and powder contact angle analysis based on Washburn method, in prerequisite that corresponding modules are purchased. (SM02 should be purchased)

- USA KINO’s innovative 3rd generation Wilhelmy plate method used Young-Laplace equation correction, in which method plate needn’t be immersed and withdrawn in measuring process (such method is called zero buoyance method).

It can be used for measurement of dynamic & static surface / interface tension, especially for viscous sample, which enriches measurement technologies of interface chemistry.

(1)Professional liquid-gas / liquid-liquid interface detection technology;

(2)Professional FK buoyancy correction technology;

(3)Professional zero point correction and preset value technology.

- Managing all dynamic live data

(2)Real-time display of data graph, with observation of interface tension changes.

The function provides unparalleled convenience in measuring dynamic surface tension of time-dependent, medium-high viscosity samples, and volatile liquid or mixture.

- Database with abundant liquid data

300 kinds of liquid with 800 data values can be directly used for analyzing surface free energy and its distributions of solid (such as Lewis acid and base components, hydrogen bond forces, polar force and dispersive force) (SM02 should be purchased)

- Powerful database management with data storage, query and modification.

(1)Real-time data storage and display, historical data searching, and eigenvalue modification are all available with CAST®1.0.

(2)CAST®1.0 saves all the measured data of dynamic value automatically and exports them into Excel.
