Description
Technical field：
The present invention relates to technical field of fertilizer manufacture, more particularly to a kind of pH detector.
Background technology：
During the manufacturing of fertilizer, need to adjust the acid-base value of fertilizer, generally by adjusting the amount of humic acid adjusting
The acid-base value of section fertilizer, during regulation, needs to determine, with the acid-base value for detecting fertilizer is seen, the amount for adding humic acid.Pass
System acid-base value detection is usually used pH indicator or pH test paper to detect, detection is got up cumbersome.In view of this technology needs,
In the urgent need to there is a kind of simple structure, a kind of easy to use, easy to detect, fireballing pH detector.
Content of the invention：
It is an object of the invention to overcoming shortcoming present in prior art, a kind of simple structure, easy to use, detection side is provided
Just, fireballing a kind of pH detector.
For achieving the above object, the invention discloses a kind of pH detector, including handle and detection probe, wherein, described
Glass electrode and reference electrode is provided with detection probe, is provided with battery case on the handle, the handle and detection probe
Between be provided with extension, live wire is set in the extension, the handle, between the extension and the detection probe
It is fixedly connected.
Detection probe is provided with open-work, built with detection liquid or test paper.
One end of the detection probe is provided with data processing module and display screen, the data processing module, described aobvious
Electrically connect between display screen, the glass electrode, the reference electrode and the battery case.
Sheath is socketed with outside the detection probe, between the detection probe and the sheath, plugs together connection.
The data processing module is used for glass electrode being converted into pH numerical value with reference electrode gained current signal and being shown
Show on a display screen.
Advantages of the present invention is：Simple structure, easy to use, easy to detect, speed is fast.Specially：The present invention is surveyed with current potential
Determine method to measure solution ph, therefore the working method of the present invention, in addition to it can measure the pH value of solution, the master of the present invention
It is glass electrode and reference electrode to want measurement part, and glass electrode is sensitive to pH, and the current potential of reference electrode is stable.By the present invention
The two electrodes be put in same solution or in medium together, just constitute a galvanic cell, and the current potential of this galvanic cell,
It is exactly the algebraical sum of this glass electrode and reference electrode current potential.The reference electrode current potential of the present invention is stable, then keep in temperature
In the case of stable, the potential change of the galvanic cell constituted by solution and electrode, only relevant with the current potential of glass electrode, and glass
The current potential of 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 of pH solution
Value.The structure of the present invention includes combination electrode and galvanometer, combination electrode indicator electrode namely described in us and reference electricity
Pole, in general the indicator electrode of the present invention is all glass electrode.The function of glass electrode be sensitive to the hydrogen ion in solution,
Potential difference is reflected with hydrionic change.The effect of reference electrode is to provide constant current potential, used as the ginseng for deviateing current potential
According to.In the part of the present invention, galvanometer is that it can capture small in the circuit of Resistance Maximum for measuring overall current potential
Potential change, and this change is showed by ammeter.Reading for convenience, the present invention have display function, are exactly
Galvanometric output signal is converted to pH reading.
