Abstract
The utility model provides a primary cell type dissolved oxygen sensor, which aims to realize that no advanced polarization is required and the sensor can be used instantly after being started when high-purity refining technology is used for preparing electrolyte primary cell, and acidic electrolyte bath prepared by adopting the high-purity refining technology requires no change on membrane and electrolyte. The primary cell type dissolved oxygen sensor comprises an anode, a cathode, an electrolyte, and ventilated membrane, and is characterized in that the anode is silver, the cathode is platinum, and the ventilated membrane is organofluorine plastic membrane. The utility model provides the primary cell type dissolved oxygen sensor better in airtightness, accuracy, stability, and convenience, longer in service life, good in quality, and lower in price for the industry.
Description
Technical field
The utility model belongs to a kind of dissolved oxygen sensor, particularly relates to a kind of film and electrolyte primary cell formula dissolved oxygen sensor of not changing.
Background technology
At present, mostly the dissolved oxygen sensor of using always on the market is polarogram formula and alkaline primary cell dissolved oxygen sensor; Its defective is that in the testing process to sample, primary need shifts to an earlier date the certain hour impressed voltage and polarizes, and can not accomplish with using with opening; Lack and troublesome maintenance second service time; General 1 to 2 months needs clean the cabin and change film and electrolyte; Not only bother the personnel that also need have certain professional technique to change; The 3rd resistant to carbon dioxide jamming performance is poor. influence accuracy of measurement and serviceable life. the tetravalence lattice are high, general every many at several thousand yuans.
Summary of the invention
In order to address the above problem, the utility model provides a kind of primary element formula dissolved oxygen sensor.Its effect is, adopts the high-purity refinement technique to prepare the electrolyte primary cell principle and need not to polarize in advance and accomplish with using with opening, and adopts the acidic electrolyte bath of high-purity refinement technique preparation really to accomplish not change film and electrolyte simultaneously.
The technical scheme that the utility model adopted is following:
A kind of primary element formula dissolved oxygen sensor comprises anode, negative electrode, electrolyte and ventilated membrane; It is characterized in that: described anode is a silver; Described negative electrode is a platinum; Described ventilated membrane is the Organic fluoride plastic foil;
Further, described negative electrode is a gold;
Further, described primary element formula dissolved oxygen sensor is provided with temperature-compensation circuit;
The beneficial effect of the utility model is: this sensor is compared with existing electrochemical dissolution lambda sensor, has following characteristics:
(1) owing to adopt acidic electrolyte bath to avoid the interference of liquid middle acid substance, good stability avoids generating the basic lead carbonate deposition, keeps negative electrode and anode surface cleaning.
(2) owing to adopt thick body electrolyte, avoid the cavity internal electrolyte solution to move about the accuracy that influence is measured owing to evaporation forms bubble.
(3) because electrolytical hyperconcetration property makes it increase serviceable life greatly, need not change electrolyte and ventilated membrane thereby can reach more than 1 year. solve electrochemical sensor and need often change a film and an electrolytical difficult problem, improved the convenience of using.
(4) since ventilated membrane by silk net reinforcing, the intensity increase is not yielding, fits closely with cathode surface, strengthens sealing.
Because the improvement of These characteristics, thus for industry provides a kind of sealing, accuracy, stability, convenience and serviceable life better inexpensive utility model sensor.
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
