Description
Technical field
The utility model belongs to species analysis Instrument technology field, specifically just relates to a kind of detachable pvc membrane electrode.
Background technology
Combination electrode has been widely used in the measurement of ion, is exactly ion compound electrode the electrode that ion electrode and contrast electrode are combined.At present in test process according to the feature of test sample, adopt different reference structures and sensitive membrane, ion compound electrode be divided into be applicable to different application in the electrode special of sample further.
The base measuring technology of ion electrode is ripe, but in actual applications, has a lot of sample to contain a large amount of suspension or thickness own, easily stick to the measuring junction of ion electrode, the performance of ion electrode is declined rapidly.Particularly to meet boundary blocked for electrode Reference system liquid, is difficult to be recovered by general cleaning method.Survey low concentration Shi Yejie circle after testing high concentration to be also not easy to clean up, the PVC film ion electrode life-span is shorter than salt film ion electrode, and dismountable structure can change film head group part increases overall electrode serviceable life.
Having occurred on the market adopting can the PVC film ion electrode of Ye Jie circle of disengaged ground, for measuring the strong sample of contaminative, but this PVC film ion electrode removable film head group part size Control is more difficult, sometimes can not reach, or contacts excessive.
Utility model content
The purpose of this utility model is exactly be difficult to control for existing PVC film ion electrode film head size of components, easily occur that loose contact cannot the technological deficiency of conducting, a kind of detachable pvc membrane electrode is provided, can ensures that electrode is connected after installing smoothly, avoid the generation of loose contact phenomenon.
Technical scheme
In order to realize above-mentioned technical purpose, a kind of detachable pvc membrane electrode of the utility model design, it comprises electrode shell, interior electrode holding pole and film head group part, interior electrode holding pole is contained in electrode shell, film head group part is contained in interior electrode holding pole front end, it is characterized in that: described interior electrode holding pole is threaded with electrode cap, spring is provided with in the electrode cap inner chamber on electrode shell top, spring props up electrode shell, the slotted eye of interior electrode holding pole front end is built with probe, pressure spring is provided with in probe, pressure spring one end props up bottom slotted eye, the other end props up probe, film head group part head is equipped with silver rod, when film head group part is installed on interior electrode holding pole front end, probe contacts with silver rod under pressure spring effect.
Further, described film head group part is threaded with interior electrode holding pole
Further, described spring housing is contained in interior electrode holding pole upper end.
Beneficial effect
The detachable pvc membrane electrode of the one that the utility model provides, pressure spring is utilized to impel probe and silver rod can tight portable box, can ensure that electrode is connected after installing smoothly, avoid the generation of loose contact phenomenon, add the safety and reliability that electrode uses.
