  Leading design of weighing sensor

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

- Better temperature drifting correction, zero tracking technology.

- Data 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 test 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.

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’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generation Wilhelmy plate method used Young-Laplace equation correction, in which method plate needn’t be immersed and withdrawn in measuring process (such method is called zero buoyance method).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 viscosity sample, which enriches measurement technologies of interface chemistry.

- Professional FK buoyancy correction technology

- Professional L-G / L-L interface detection technology

- Professional zero point correction and value preset technology

 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 A10 are equipped with both weighing sensor calibration and self-calibration function for sensing interface (Wilhelmy plate and DuNoüy ring), which is much better than other manufacturers’. It can enable you to control reliability of measured value more effectively.

 Managing all dynamic live data

- Software manages all live data that balance acquired. All data can be query and modified as well as exported to Excel.

- 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.

 Powerful database management with data storage, query and modification

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

-CAST®1.0 saves all measured data of dynamic value automatically and exports them into Excel.
