Abstract
The utility model relates to a high-precision soil corrosion measuring device; which is composed of a working electrode with lead-out wires, an electrolytic cell and a detecting device; the electrolytic cell is composed of three electrodes of refrence and auxiliary electrodes, a container fixed on the three electrodes and inner medium thereof. The utility model is characterized in that the reference electrode passes through and is insulation fixed on a shaft center hole of the column-shaped working electrode; the side surface of the container corresponding to the auxiliary electrode is provided with a fixing circular hole of the working electrode. Consequently, the reference electrode is close to the working electrode; the influence of high resistance of the medium is reduced; the measuring result and accuracy become much better.
Description
The utility model relates to a kind of high precision soil corrosion measurement device.
The corrosion behavior of measuring metallic materials in medium (as soil or seawater), need to use existing three electrode measurement system or devices, its basic structure is to have plastics or glass container to be fixed can make three electrodes, make the surface of the as far as possible close working electrode of contrast electrode during measurement, but also limited; When measuring the higher medium of sea water conductivity, because its conductivity height, the ohmmic drop is just little, and the error that is caused by it is also little, can also be suitable for.But during the corrosion behavior in the structural metallic materials soil such as research iron and steel, the dielectric resistance of soil is very big, and less polarization current just can produce bigger dielectric resistance ohmmic drop.And because the obstruction of soil particle, in fact contrast electrode is difficult near working electrode surface.In addition and since contrast electrode from the front near working electrode, also can shield a part of line of electric force, also can cause measuring error.
The purpose of this utility model is to overcome above shortcoming, and a kind of high precision soil corrosion measurement device that improves measuring accuracy is provided.
The utility model is to working electrode, and the improvement of the prior art that electrolytic cell that contrast electrode and auxiliary electrode constitute and pick-up unit are formed is about to bore on the column working electrode 2 an axle center hole.Contrast electrode passed and insulate be fixed in wherein, with research surface near working electrode.
The utility model is simple in structure, the precision height, and cost is low, and is easy to use.
Further specify the utility model below by embodiment and accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a decomposing schematic representation of the present utility model.
The utility model is the working electrode 2 by band extension line 6, contrast electrode 4 is formed with the electrolytic cell and the pick-up unit (figure slightly) of medium 7 formations of 5 three electrodes of auxiliary electrode and fixing above-mentioned three electrode container 1 and Qi Nei, it is characterized in that contrast electrode 4 passes and the axle center hole 3 that is fixed in column working electrode 2 that insulate in, with working surface near working electrode, be that contrast electrode 4 passes hole 3 near the research surface from the back side of working electrode 2, thereby greatly reduce the high-resistance influence of medium, make measurement result more near actual conditions.The circular hole 8 of a steady job electrode 2 is set on the side of the relative container 1 of auxiliary electrode 5 for this reason.
