Abstract
The utility model discloses a kind of portable dissolved oxygen meter, it relates to environment supervision instrument technical field.It comprises main frame, test electrode, temp probe, draw-in groove and hangers, described main frame is nested in draw-in groove, draw-in groove both sides are fixed with a pair hangers, described test electrode is all connected with main frame by data line with temp probe, and described test electrode and temp probe are embedding respectively to be hung in each self-corresponding hangers.Its structure of the utility model is simple, easy to use, can provide a hanger effectively deposited in real time with relay testing electrode and temp probe, to extend its serviceable life.
Description
Technical field
The utility model relates to environment supervision instrument technical field, is specifically related to a kind of portable dissolved oxygen meter.
Background technology
Dissolved oxygen DO refers to the molecular oxygen be dissolved in water, is usually denoted as D0, represents by the milligram number of often liter of water oxygen and saturation percentage.In the saturated content of dissolved oxygen DO and air, the dividing potential drop of oxygen, atmospheric pressure, water temperature and water quality have close relationship; DO determination be in monitoring water environment one must survey index; Dissolved oxygen meter is the device measuring oxygen in water, and its principle of work is that oxygen is reduced by working electrode through barrier film, producing the dissufion current be directly proportional to oxygen concentration, by measuring this electric current, obtaining the concentration of oxygen in water.Existing portable dissolved oxygen meter is when frequent test sample and after being completed, and test electrode and temp probe are just arbitrarily put, and so easy damage test electrode and temp probe, reduce its serviceable life.
Utility model content
The purpose of this utility model is to provide a kind of portable dissolved oxygen meter, it solves how in whole dissolved oxygen DO test process, deposits the technical matters with relay testing electrode and temp probe in real time.
The purpose of this utility model is achieved through the following technical solutions:
A kind of portable dissolved oxygen meter, comprise main frame, test electrode, temp probe, draw-in groove and hangers, described main frame is nested in draw-in groove, draw-in groove both sides are fixed with a pair hangers, described test electrode is all connected with main frame by data line with temp probe, and described test electrode and temp probe are embedding respectively to be hung in each self-corresponding hangers.
Further, the subassembly of described draw-in groove and hangers is that integrated injection moulding is made, can with main frame disassembled and assembled freely.
The beneficial effects of the utility model are:
Its structure of the utility model is simple, easy to use, can provide a hanger effectively deposited in real time with relay testing electrode and temp probe, to extend its serviceable life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number description:
1. main frame; 2. test electrode; 3. temp probe; 4. draw-in groove; 5. hangers.
Embodiment
Referring to Fig. 1, the utility model embodiment is by the following technical solutions: it comprises main frame 1, test electrode 2, temp probe 3, draw-in groove 4 and hangers 5, described main frame 1 is nested in draw-in groove 4, draw-in groove 4 both sides are fixed with a pair hangers 5, described test electrode 2 is all connected with main frame 1 by data line with temp probe 3, and described test electrode 2 and temp probe 3 are embedding respectively to be hung in each self-corresponding hangers 5; The subassembly of described draw-in groove 4 and hangers 5 is that integrated injection moulding is made, can with main frame 1 disassembled and assembled freely.
According to above-mentioned structure, in the test process of whole dissolved oxygen DO, main frame 1 is nested in draw-in groove 4 by operator, then according to actual needs, deposits test electrode 2 and temp probe 3 in real time in hangers 5, to protect it not to be damaged, extends its serviceable life.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
