Description

A kind of accurate PH meter
Technical field
The utility model relates to field of medical examination, particularly relates to a kind of accurate PH meter.
Background technology
PH inspection is the Interventions Requested checking section office the most frequently used, and existing PH inspection adopts subsidiary in artificial test strips or heavy-duty machines inspection.When needing to check separately PH, often cannot obtain accurate pH value.Existing PH meter is usually also fairly simple on the market, adopts the pH value of the mechanical arm test measured object of leakage, often affects the accuracy of detection because of extraneous factor.Therefore, need a kind of PH of precision to count, pH value can be detected more accurately.
Utility model content
The utility model technical issues that need to address are to provide a kind of accurate PH meter, can detect pH value more accurately.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of accurate PH meter, comprise base, be arranged on main frame on base and detection case, described base is also provided with action button and articles holding table, before described main frame, is connected with display screen; And,
Described detection case inner top is provided with mechanical arm, and described mechanical arm bottom is provided with anode probe and cathodic probe, described anode probe and the isolation of cathodic probe mutually insulated;
Be provided with control module in described main frame, described control module electrical connection mechanical arm, action button and display screen, described anode probe and cathodic probe are respectively by wire connection control unit.
Further, described mechanical arm comprises fixed arm and lower telescopic arm, and described anode probe and cathodic probe are connected on lower telescopic arm.
Further, described articles holding table is lower than the bottom surface of described detection case.
Further, described action button is positioned at before described display screen in inclined-plane.
The beneficial effects of the utility model are: the impact that the utility model adopts embedded detection case to prevent external environment to cause PH, telescopic mechanical arm, better control, to the detection of determinand, is analyzed pH value by the electric signal obtaining negative electrode and anode, can be detected pH value more accurately.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of accurate PH meter of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, base, and 2, main frame, 3, display screen, 4, action button, 5, detection case, 6, articles holding table, 7, mechanical arm, 8, anode probe, 9, cathodic probe.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1, the utility model embodiment comprises:
A kind of accurate PH meter, comprise base 1, be arranged on main frame 2 on base 1 and detection case 5, detection case 5 holds the container of detected solution for placing.Described base 1 is also provided with action button 4 and articles holding table 6, described articles holding table 6 is lower than the bottom surface of described detection case 5, and articles holding table 6 can place the container of solution to be measured temporarily, or on articles holding table 6 proportioning solution.Described main frame 2 is above connected with display screen 3, and display screen 3 show the pH value recorded, and it is inclined-plane above that described action button 4 is positioned at described display screen 3, can pressing operations button 4 more easily.
Described detection case 5 inner top is provided with mechanical arm 7, described mechanical arm 7 comprises fixed arm and lower telescopic arm, described lower telescopic arm bottom is provided with anode probe 8 and the cathodic probe 9 of mutually insulated isolation, the pH value of different depth solution is got in the flexible spy of mechanical arm 7, and anode probe 8 and cathodic probe 9 obtain the electric signal of solution respectively.
Control module is provided with in described main frame 2, described control module electrical connection mechanical arm 7, action button 4 and display screen 3, described anode probe 8 and cathodic probe 9 are respectively by wire connection control unit, the stretching, extension of control module controller mechanical arm 7 and retraction, obtain the instruction of action button 4 and perform instruction, analyze the electric signal of anode probe 8 and cathodic probe 9 acquisition and draw pH value, the pH value obtained is presented on display screen 3.
The operation steps of a kind of accurate PH meter of the utility model is as follows: be placed on by the container filling determinand solution on articles holding table 6, after suitable proportioning, container is put in detection case 5, the instruction that behaviour does mechanical arm 7 is sent by action button 4, control module acquisition instruction rear drive mechanical arm 7 in main frame 2 stretches to correct position and tests solution, obtain the ion-conductance signal in solution after anode probe 8 and cathodic probe 9 contact with solution, draw pH value by control module analysis and be presented on display screen 3.
The impact that the utility model adopts embedded detection case to prevent external environment to cause PH, telescopic mechanical arm, better controls the detection to determinand, analyzes pH value, can detect pH value more accurately by the electric signal obtaining negative electrode and anode.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
