The specification of the copper sulfate reference electrode is: diameter 3cm length 15cm
.
First, the use of features
Portable copper sulfate reference electrode is suitable for field use. Mainly for the natural potential of cathodic protection potential and the determination of underground metal pipelines, determination of stray current, also can be used as an additional control potential current cathodic protection system by reference electrode can be used for the potentiometric determination of reinforced concrete and the cable metal sheath.
The electrode can be used in the place where the soil is sticky, as well as various kinds of soil and fresh water.
Two, structural performance
1, small volume, easy to carry. The cavity is made of transparent organic glass, which is convenient for observing the saturation of the copper sulfate solution.
2, the electrode potential stability, standard conditions of potential calomel electrode was 70 + 3mV, consistent with the theoretical value, the potential difference between each other is less than 1mV.
3, the electrode is not easy to polarization, the use of the field, the potential difference between each other is less than + 3mV. Electrode resistance less than 3K.
4. The electrode life is long, the electrode cap is connected with the electrode cavity by a screw hole, and the filling solution is convenient. The utility model can be used for more than one year, so long as the cavity is not damaged, the utility model can be used for a plurality of times.
5, the electrode structure is firm, corrosion resistance, microporous membrane leakage rate is appropriate, no visible liquid flow, can be placed in the pocket.
Three, the use of methods
1, the reference electrode of the insuranceindustry, injection of distilled water to the copper sulfate particles above 2cm after the front cover, shaking several times, the copper sulfate particles fully dissolved;
2, the reference electrode of the gas plug into the water soaked;
3, the reference electrode is inserted into the end of the metal structure in the vicinity of the wet soil, the multimeter is adjusted to the range of the 2V file, the reference electrode with the wire clamp the black end of the multimeter;
4, the multimeter red line clamp test pile test line, read and record data.
