Advanced sample stage control system to fully enhance accuracy of traversing and positioning of sensing interfaces (e.g. platinum plate, DuNoüy ring)

- USA KINO is the only enterprise that has comprehensively studied and produced precision vertical travel positioning stage and applied it into interface chemistry analytical system. - We uniquely adopt coupler to connect motors and mechanical moving parts directly, which avoids problems of backlash and poor control accuracy caused by belt pulley connection structure. - The adoption of auto control of stepping motor and motion control card fully enhanced accuracy and compatibility of positioning control. For special measurement requirements.

    Anti-static design to improve measurement accuracy of surface/interface tensions (for option)

- USA KINO adopts ionic wind technology to avoid detection error of liquid-gas interface caused by electrostatic. When there’s electrostatic existing, liquid interface will rise, sensing interface (plate or ring) will contact with it ahead of time, hence measurement value of surface tension will be larger than normal, for example, measured value is 71.214mN/m with electrostatic and 70.891mN/m when using antistatic kit. - 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.
