Description
Technical field
The utility model relates to the instrument that chemical products detect, particularly a kind of chemical industry solutions product acid base number analyzer.
Background technology
The mensuration of chemical industry solutions product acid base number generally adopts the method for hand sampling, chemistry titration; Owing to take a sample in the production scene; Analyze to the laboratory, cause analysis result to lag behind production, incured loss through delay optimised process and adjusted opportunity; Bring corresponding difficulty for the control of technology, product quality can not effectively be guaranteed.If environment is abominable, like this hand sampling number of times limited, can not continuous on-line detection, many human factors are difficult to guarantee measuring accuracy; Long from being measured to change solution concentration required time simultaneously, the solution concentration fluctuation is big.Measure the pH value of solution through pH test paper change in color, can receive the interference of materials such as solution intrinsic colour or protein and be limited to adopt, only be applicable to measurement greater than the 0.5pH value; Measurement for less than the 0.5pH value then can't be carried out.
Summary of the invention
In order to solve the problem that background technology exists; The technical scheme that adopts is following: a kind of chemical industry solutions product acid base number analyzer; Comprise control module, capacity module, potential measurement module, display module composition, it is characterized in that: capacity module, potential measurement module, the parallel link control module of display module.Described control module is made up of electrode holder, electromagnetic propeller, single-chip microcomputer, single-chip microcomputer connection electrode folder, electromagnetic propeller.Described capacity module is made up of the clear glass material.Described potential measurement module is made up of glass electrode, silver electrode.Described display module is made up of the segmentation liquid crystal.
This novel advantage is safe and reliable, shortening Measuring Time.
Measuring principle is: form primary element when the reversible indicator electrode of hydrogen ion and a contrast electrode are immersed in a certain solution simultaneously, form the charging process of ion, and form certain potential difference (PD); Produce an electromotive force at a certain temperature; This electromotive force is relevant with the hydrogen ion activity of solution, and very little with the existence relation of other ion, if excessive hydrogen ion; Then solution is acid; Then be alkalescence on the contrary, glass electrode is to hydrogen ion adsorptive power selectively, and what of absorption quantity are directly proportional with pH; The glass electrode surface adsorption behind the hydrogen ion can with the solution formation electric potential difference in the glass bead, just can record the electric potential difference of the entire circuit relevant again with pH with contrast electrode, can confirm the potential of hydrogen of solution by this relation.
Description of drawings
The measurement block diagram that Fig. 1 provides for the utility model;
Fig. 2 is the appearance assumption diagram of the utility model.
Embodiment
Be illustrated in figure 1 as the measurement block diagram that the utility model provides, comprise control module, capacity module, potential measurement module, display module composition, capacity module, potential measurement module, the parallel link control module of display module.
When using, the chemical industry solutions of opening 3 measurements of clear glass material among Fig. 2 gets into, and starts single-chip microcomputer 5; Electrode holder 1 descends, and glass electrode 2 is got in the chemical industry solutions of test, and silver electrode 4 powers up through single-chip microcomputer 5; Measure beginning, silver electrode 4 produces potential difference (PD) with glass electrode 2, at 25 ℃; 1 pH unit of every variation in the solution, potential difference (PD) is changed into 59.16 millivolts, can confirm the potential of hydrogen of solution according to the potential difference (PD) graduation apparatus; Electromagnetic propeller 6 makes the piston 7 cleaning test solution that advances, and prevents secondary pollution.Single-chip microcomputer 5 control electrodes folder 1 and electromagnetic propeller 6 among Fig. 2, no matter whether electrode holder 1 descends, and electromagnetic propeller 6 can be worked.
