Abstract
The invention provides a use method of a detector. The detector measures a pH value of a solution by potentiometry. Therefore, except for the measurement of the pH value of the solution, main measurement components of the detector are a glass electrode and a reference electrode, wherein the glass electrode is sensitive to pH, while the reference electrode is stable in potential. The two electrodes of the detector form a primary battery after being placed into the same solution or medium, and the potential of the primary battery is an algebraic sum of potentials of the glass electrode and reference electrode. The detector is simple in structure, convenient to use and detect, and high in speed.
Description
Technical field:
The present invention relates to the Production of manure technical field, particularly a kind of detector and using method thereof.
Background technology:
In the manufacturing process of fertilizer, need to regulate the potential of hydrogen of fertilizer, the potential of hydrogen of usually regulating fertilizer by the amount of regulating humic acid in adjustment process, need to determine to add with the potential of hydrogen of seeing detection fertilizer the amount of humic acid.Classical acid basicity detects and usually detects with pH indicator or pH test paper, detects cumbersome.In view of this Technology Need, a kind of simple in structure, easy to use, easy to detect in the urgent need to occurring, fireballing a kind of detector and using method thereof.
Summary of the invention:
The object of the invention is to overcome the shortcoming that exists in the prior art, provide a kind of simple in structure, easy to use, easy to detect, fireballing a kind of detector and using method thereof.
For achieving the above object, the invention discloses a kind of detector, comprise handle and detection probe, wherein, be provided with glass electrode and contrast electrode on the described detection probe, be provided with battery case on the described handle, be provided with extension between described handle and the detection probe, be provided with electric wire in the described extension, described handle is fixedly connected with between described extension and the described detection probe.
One end of described detection probe is provided with data processing module and display screen, is electrically connected between the described data processing module, described display screen, described glass electrode, described contrast electrode and described battery case.
Described detection probe outer cover is connected to sheath, plugs together between described detection probe and the described sheath to be connected.
Described data processing module is used for glass electrode and contrast electrode gained current signal are converted into pH numerical value and are presented at display screen.
Advantage of the present invention is: simple in structure, easy to use, easy to detect, speed is fast.Be specially: the present invention measures pH with potentiometry, so working method of the present invention, except the pH value that can measure solution, main measurement component of the present invention is glass electrode and contrast electrode, glass electrode is responsive to pH, and the current potential of contrast electrode is stable.These two electrodes of the present invention are put into same solution or medium together, just consisted of a primary element, and the current potential of this primary element is exactly the algebraic sum of this glass electrode and contrast electrode current potential.Contrast electrode current potential of the present invention is stable, so in the situation that temperature keeps stable, the potential change of the primary 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, just can draw the pH value of pH solution.Structure of the present invention comprises combination electrode and galvanometer, and combination electrode is our said indicator electrode and contrast electrode namely, and in general indicator electrode of the present invention all is glass electrode.The function of glass electrode is responsive to the hydrogen ion in the solution, reflects potential difference (PD) with hydrionic variation.The effect of contrast electrode provides constant current potential, as the reference that departs from current potential.In the parts of the present invention, galvanometer is be used to measuring whole current potential, and it can capture small potential change in the circuit of Resistance Maximum, and this variation is showed by ammeter.In order to make things convenient for reading, the present invention has Presentation Function, has converted galvanometric output signal to the pH reading exactly.
