Abstract
The invention relates to a composite micro pH electrode, which comprises an injection molding shell, an indicating electrode system, a reference electrode system and a filamentary silver lead, wherein the injection molding shell serves as an electrode shell; the indicating electrode system and the reference electrode system are arranged inside the injection molding shell; the filamentary silver lead is arranged at the back end of the injection molding shell through an electrode lead-out wire interface respectively; the overall length of the injection molding shell is 4 millimeters; and the bottom surface diameter of the injection molding shell is 3 millimeters. The invention has the advantages that: the electrode is suitable for small spaces or trace amount of tested liquid; an electrolyte coating technology is adopted and a solid structure is arranged, so that the problems of leakage, back flow, waterproofness and the like are solved, and the electrode is not limited by any angle and direction during operation and is suitable for various complex specific environments; sensitive metal is taken as a reaction end, so that the electrode is firm, is convenient for transportation, carrying and maintenance and is prevented from being corroded by hydrofluoric acid; and after transportation, storage and sealing off, the electrode can directly enter a measuring state.
Description
Technical field
The present invention relates to sensor technical field, specifically a kind of combined type minisize pH electrode.
Background technology
In the specialty chemical field, the expression of Acidity of Aikalinity pH value size commonly used is surveyed the general PH of employing of pH value electrode and is tested; Common pH electrode is by pH sensing glass film chemistry amount H+ ion in the detected solution to be converted to measurable value of electrical signals, so the pH electrode is defined as the electrochemical sensor to the H+ ion-sensitive again.In existing combined type pH electrode structure, generally form by the internal reference electrode or the outer contrast electrode that are arranged in the housing; But present compound pH electrode sensor length is all greater than 10cm, its rear end link lead, inner glass sensitive membrane conductive material and sensor can only be placed vertically or tiltedly put and just can flow out test by electrolyte and constitute cell circuit.
The above existing like product of analyzing structurally exists serious deficiency, be embodied in: first, on the electrode external form, the existing common electrode of like product is divided into two kinds of industrial electrodes and laboratory electrode, the former does not have buttock line and external form length and diameter and is about 150mm and 31mm respectively, the latter does not have buttock line and external form length and diameter and is about 100mm and 12mm respectively, and key is that this series products is not suitable for using in the small space or in micro-test solution; The second, from electrode structure, must inject the electrolytic solution of liquid state, glue or solid in the indication of existing like product and the contrast electrode, its shortcoming is in use being vertical angle, for ease of the outflow and the ionic communication of electrolytic solution; The 3rd, on the electrode manufacture craft, the indication and the contrast electrode of existing like product are the glass sensitive membrane as its reactive end, and its shortcoming is apparent, can cause glass-film easily broken under numerous regular situations such as transportation, maintenance, use, and the corrosion that can't resist hydrofluoric acid solution; The 4th, from using, this series products, should soak in activating solution after tens of minutes before using transporting, deposit, sealing off the back, and flow processs such as to be calibrated and demarcation are finished, and the measurement state of being allowed for access exists long defective of running time.
Summary of the invention
At above defective, the invention provides a kind of length and diameter small, adopt electrolytic solution to be coated with that membrane technology, waterproof are anti-ly let out, sturdy and durable, the combined type minisize pH electrode that can carry out comprehensive measurement, unreasonable and cause many deficiencies to solve existing structure in external form, parts, technology and application facet.
For achieving the above object, the present invention is by the following technical solutions:
A kind of combined type minisize pH electrode, comprise injection casing, indicator electrode system, contrast electrode system and filamentary silver lead-in wire, the electrode shell body is an injection casing, described injection casing inside is provided with indicator electrode system and contrast electrode system, and this injection casing rear end is provided with the filamentary silver lead-in wire by the electrode outlet line interface respectively; Described injection casing entire length is 4mm, and its bottom surface diameter is 3mm; Described injection casing entire length can be less than 4mm, and its bottom surface diameter can be less than 3mm.
The beneficial effect of combined type minisize pH electrode of the present invention is: entire length is about 4mm, and the bottom surface diameter is about 3mm, can be fit to use in the small space or in micro-test solution; Adopt the electrolytic solution coating technology, solid structure is set and do not have leakage, pour in down a chimney, problem such as waterproof, in utilization, be not subjected to the restriction in any angle and orientation, be adapted at using in all kinds of complicated specific environments; The employing sensitive metal is a reactive end, firm, the transportation carry, safeguard convenient, not corroded by hydrofluorite; After transporting, depositing, seal off, can directly enter the measurement state, easy to use.
