In order to solve above technical matters, the whole value measuring method of coin type objects not damaged of the present invention comprises following basic step:
1), the sealing of coin type objects periphery is placed insulator;
2), set up sealing fluid injection chamber respectively in the coin type objects both ends of the surface;
3), conductive liquid is introduced two sealing fluid injection chambeies, and connect electrode;
4), measure two interelectrode predetermined electricity physical parameters (for example resistance value) this moment;
5), will carry out geometric operation (for example deducting conductive liquid self-resistance value) with the electricity physical parameter of the above-mentioned electricity physical parameter of measuring (for example resistance value) and conductive liquid self, obtain a result.
The basic structure that realizes said method special measurement instrument is, this instrument comprises support, described mid-stent is equipped with the coin retainer plate that insulating material is made, described retainer plate endoporus and coin type objects cylindrical to be measured are sealed and matched, the involutory left and right locking member that can relatively move is equipped with in the both sides, the center circle that is shaped on aperture and coin type objects equal diameters to be measured on the involutory surface of described two locking member inboards is recessed, is shaped on liquid injection hole near the recessed openend of this circle, and described two locking member outer ends are connected to electrode respectively.
