Between pollution, it is therefore desirable to it is every examined and determine a kind of reagent after probe is cleaned, then carry out another reagent again
Calibrating, complex operation, and expend the more time.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of chemical pH detectors.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of chemical pH detectors, including main frame and probe, the upper end of the probe is fixedly connected with the main frame, described
Probe electrically connects with the detection circuit in the main frame, and the detector also includes one-level spacer, two level spacer and three-level spacer,
Lateral surface of the upper end of the one-level spacer, the two level spacer and the three-level spacer from top to bottom successively with the probe is consolidated
Fixed connection, the lower end of the one-level spacer, the two level spacer and the three-level spacer is provided with elastic seal ring.
Specifically, the one-level spacer, the two level spacer and the three-level spacer are the rubber elastic membrane of tubulose, institute
The distance for stating the upper end of one-level spacer and the lower end of the probe is less than the length of the one-level spacer, the two level spacer it is upper
The distance between end and the lower end of the probe are less than the length of the two level spacer, upper end and the spy of the three-level spacer
The distance between lower end of pin is less than the length of the three-level spacer.
Specifically, the hypomere of the two level spacer is sleeved on the outside of the one-level spacer, the hypomere set of the three-level spacer
On the outside of the two level spacer.
The beneficial effects of the utility model are：
A kind of chemical pH detectors of the utility model make it in one kind by setting multistage spacer on the probe of detector
It after the reagent of type has detected, can be overturn probe environmental sealing, avoid causing when carrying out a kind of measurement of lower reagent
Reagent contamination.
Brief description of the drawings
Fig. 1 is a kind of structural representation of chemical pH detectors described in the utility model；
Fig. 2 is the structural representation of probe described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, a kind of chemical pH detectors of the utility model, including main frame 1, probe 2, one-level spacer 3,
Two level spacer 4 and three-level spacer 5, the upper end of probe 2 are fixedly connected with main frame 1, and probe 2 is electrically connected with the detection circuit in main frame 1
Connecing, the lateral surface of the upper end of one-level spacer 3, two level spacer 4 and three-level spacer 5 from top to bottom successively with probe 2 is fixedly connected, and one
The lower end of level spacer 3, two level spacer 4 and three-level spacer 5 is provided with elastic seal ring 6, one-level spacer 3, two level spacer 4 and three
Level spacer 5 is the rubber elastic membrane of tubulose, and the distance of the upper end of one-level spacer 3 and the lower end of probe 2 is less than one-level spacer 3
Length, the distance between the upper end of two level spacer 4 and the lower end of probe 2 be less than two level spacer 4 length, three-level spacer 5 it is upper
The distance between end and the lower end of probe 2 are less than the length of three-level spacer 5, and the hypomere of two level spacer 4 is sleeved on outside one-level spacer 3
Side, the hypomere of three-level spacer 5 are sleeved on the outside of two level spacer 4.
A kind of operation principle of chemical pH detectors of the utility model is as follows：
Before use, one-level spacer 3, two level spacer 4, three-level spacer 5 are in turning over the lower end of state, i.e. one-level spacer 3
Top at its upper end, the lower end of two level spacer 4 top at its upper end, the lower end of three-level spacer 5 are at its upper end
Top.
When examining and determine the first reagent, by by the part between the lower end of probe 2 and the upper end of one-level spacer 3
Probe 2 is placed in reagent, then the PH of reagent can be examined and determine, and after the completion of calibrating, will be turned under one-level spacer 3, close in elasticity
Under the sealing of seal 6, make one-level spacer 3 that the used part of probe 2 is carried out into sealing closing.
When examining and determine second of reagent, by the part probe 2 between the lower end of probe 2 and the upper end of two level spacer 4
It is placed in reagent, PH calibratings, calibrating is carried out by the part of probe 2 between the upper end of one-level spacer 3 and the upper end of two level spacer 4
After the completion of, it will be turned under two level spacer 4, this used part sealed.
Similarly, when the third reagent is examined and determine, by between the lower end of probe 2 and the upper end of three-level spacer 5
Part probe 2 is placed in reagent, is examined and determine by the part probe 2 between the upper end of two level spacer 4 and the upper end of three-level spacer 5,
After the completion of calibrating, it will be turned under three-level spacer 5.
Other, if it is desired, it can continue to set level Four spacer, Pyatyi spacer etc..
