Description
Technical field
The present invention relates to sensor field, more particularly to a kind of modified model pH value sensor.
Background technology
PH meter is to measure the important tool with reaction solution acid-base value, model and the product of pH meter are varied, and display mode also has pointer to show and numerical monitor two kinds is optional, but no matter how the type of pH meter changes, its operation principle is all identical, and its main body is an accurate potentiometer.
PH meter measures solution ph with potentiometry, therefore the working method of pH meter, except measuring the pH value of solution, it is also possible to measure the electromotive force of battery.PH, in Latin, is the abbreviation of Pondushydrogenii, is hydrionic activity in material, and pH value is then the negative of the logarithm of hydrogen ion concentration.
The main measurement parts of pH meter are glass electrode and reference electrode, and glass electrode is sensitive to pH, and the current potential of reference electrode is stable.The two electrode of pH meter is put in same solution together, just constitutes a galvanic element, and the current potential of this galvanic element, it is simply that the algebraical sum of this glass electrode and reference electrode current potential.
The reference electrode current potential of pH meter is stable, so when temperature remains stable for, the potential change of the galvanic element that solution and electrode form, only relevant with the current potential of glass electrode, and the current potential of glass electrode depends on the pH value of solution to be measured, therefore by the measure of the change to current potential, it is possible to draw the pH value of pH solution.
The glass ball bulb of the glass electrode of pH value detecting instrument is easy to crush; and cause pH tip damage; although being provided with protection catch around the glass ball bulb of the glass electrode of existing pH value detecting instrument; but glass ball bulb can not omnibearing be protected by protection catch, is easily broken when encountering the thrust bottom the edge of the container equipped with solution to be measured or solution to be measured bottom glass ball bulb.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that a kind of modified model pH value sensor, solve the problem that the glass ball bulb of existing pH value sensor is susceptible to crush.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
A kind of modified model pH value sensor; it includes pH probe, sensor main body; described pH probe is connected by wire with sensor main body; described pH probe is provided with protective cover; the glass ball bulb of described pH probe is positioned at inside protective cover, and described pH probe is provided with travel(l)ing rest and snap ring, and described travel(l)ing rest coordinates installation with pH probe; the probe of described pH probe can at travel(l)ing rest internal slide, and described snap ring is positioned at inside travel(l)ing rest.
Further; described travel(l)ing rest includes the protection ring, pillar and the base that are sequentially connected with; described pillar is provided with card column; described snap ring is provided with draw-in groove; described draw-in groove includes interconnective pillar slideway and back-shaped draw-in groove; described travel(l)ing rest is connected with snap ring by pillar, draw-in groove, and described base is circulus.
Further, described pH probe is provided with top cap.
Further, described protective cover is the network structure of hollow out.
Further, described protective cover, travel(l)ing rest and snap ring are that nonmetallic materials are made.
Compared with prior art, the invention has the beneficial effects as follows:
1, protective cover of the present invention can be protected glass ball bulb is comprehensive; the protective cover of the present invention is rigid network structure; contacting of solution to be measured and glass ball bulb will not be hindered; also allow for cleaning simultaneously; absorbent paper is covered the moisture inside and outside protective cover then can be blotted by protective cover; absorbent paper is stretched into inside protective cover by the mesh of protective cover, then the moisture on glass ball bulb can be purged.
2, pH detection position the most accurately should be the central authorities of liquid, chamber wall can not be close to, so the data of detection are accurately more convincing, therefore pH probe it is frequently necessary to artificially hold, when stabilization time is longer, then needing erection bracket, it has not been convenient to the operation of experimenter, the setting of the present embodiment travel(l)ing rest and snap ring facilitates laying of pH probe.Travel(l)ing rest with pH probe for track, can slidably reciprocate, so can according to the height and position of the altitude mixture control glass ball bulb of liquid, and travel(l)ing rest can be fixed by snap ring, has so been easy to the operation of experimenter.
3, base of the present invention is circulus, so can by the pH glass ball bulb popped one's head in removal travel(l)ing rest, it is simple to glass ball bulb is carried out.
4, the cooperation snap ring that arranges of top cap of the present invention can ensure that travel(l)ing rest can only slidably reciprocate on pH pops one's head in, convenient operation.
5, protective cover of the present invention, travel(l)ing rest and snap ring are that nonmetallic materials are made, it is to avoid the present embodiment impact on solution acid alkalinity.
