C, with battery case and data processing module, display screen, galvanometer, contrast electrode connects by electric wire between the glass electrode;
D, plug together the connection upper jacket in the detection probe outside.
Through manufacture method of the present invention, the fertilizer detector for pH value that makes, 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: method is simple, and is easy to use, easy to detect, and 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.
