Bottle and nitrogen cylinder, the oxygen cylinder bottleneck and nitrogen cylinder bottleneck are respectively equipped with flow control switch, on the flow control switch
Portion is connected with appendix, and the appendix is stretched into reactive tank, and stretches out reactive tank along reaction tank bottom, the gas transmission in reactive tank
Pipe upper surface is provided with some apertures, and solution to be measured is filled in the reactive tank, be placed with the solution stirring rod, normal electrode and
It is calibrated electrode.
Preferably, the reactive tank is isothermal reaction groove.
Preferably, the stirring rod is glass stirring rod.
Preferably, the appendix is rubber hose.
The utility model has the advantage of：It is simple in construction, it is easy to operate, intuitively it can find out whether be calibrated electrode very
Standard, while the controlling switch on oxygen cylinder and nitrogen cylinder is opened, and the flow of gas is controlled, two gases is mixed
Afterwards, the concentration of oxygen is not more than the concentration after solution oxygen saturation to be measured, and mixed gas is passed through in reactive tank along appendix,

The characteristics of determining, avoid because the change of solution temperature causes the difference of oxygen content.
In the present embodiment, the stirring rod 8 is glass stirring rod, and glass bar is not easy to react with solution.
In the present embodiment, the appendix 5 is rubber hose.
Operation principle and methods：The controlling switch 4 on oxygen cylinder 2 and nitrogen cylinder 3 is opened simultaneously, and controls gas
Flow, after two gases is mixed, the concentration of oxygen is not more than the concentration after solution oxygen saturation to be measured, by mixed gas
It is passed through along appendix 5 in reactive tank 1, the surface of appendix 5, which is provided with some apertures, can make mixed gas maximumlly into molten
In liquid, stirring rod 8 can help oxygen Quick uniform to be dissolved in prepare liquid, improve operating efficiency, save the time, will mark
Collimator electrode 7 is placed in solution to be measured, observes the reading of simultaneously record standard electrode, then will be calibrated electrode 6 and be placed in solution to be measured,
Observe and record and be calibrated electrode reading, adjust mixed gas concentration, measure again, obtain two group number-readings and contrasted, if
Reading is consistent, then is calibrated the accuracy of reading of electrode 6, if it is different, then explanation is calibrated the read untrue of electrode 6.
As known by the technical knowledge, the utility model can pass through other essence without departing from its spirit or the reality of essential feature
Scheme is applied to realize.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only
's.It is all in the scope of the utility model or in the change being equal in the scope of the utility model by the utility model bag
