SYSTEM WITH KELVIN PROBE WITH ROTATING OUTER SURFACE OF PROBE Russian patent published in 2019 - IPC G01N27/00 G01R1/07 

FIELD: physics.

SUBSTANCE: system (100) with a Kelvin probe for analysis of analysed sample (134), comprising drive (102), controlled and driven by means (103) of the drive/power supply control, for rotation of element (106, 120) around the axis of rotation; connected to drive (102) head (120) with a Kelvin probe, having Kelvin probe (122) and having outer surface (124) of a Kelvin probe on one end; characterized in that the outer surface of the Kelvin probe is located on the side surface with respect to the axis of rotation of the head with the Kelvin probe. Calibration system for a Kelvin probe system (100) and a measurement method using a Kelvin probe system (100) for determining the presence of hydrogen are also disclosed.

EFFECT: technical result when implementing the declared group of inventions is high accuracy of analysing the analysed object, namely providing the possibility of avoiding interference, reducing the degree of damage of the probe during analysis, and, besides, constant self-calibration.
