Description
Technical Field
The invention relates to the technical field of chlorine testers, in particular to a method for testing and calibrating an electronic digital display chlorine tester and the tester.
Background
The chlorine tester is mainly used for rapidly measuring the conductivity of a disinfectant solution (such as sodium hypochlorite, 84 disinfectant and the like). The disinfectant is widely applied to the sanitary disinfection of hospitals, public places and the like; such as various medical devices, door handles, window handles, light buttons, electrical switches, carpets, furniture surfaces, telephone microphones and keys, interphones, computer keyboards and mice, toys, etc.; sanitation and disinfection of families; such as the disinfection of vegetables, fruits, tableware, textiles, etc.
According to the record, the high-grade people's court of Beijing City examines and finds out: in 1984, the first infectious disease hospital in Beijing, the predecessor of the ground altar hospital, developed a disinfectant solution with the function of rapidly killing various hepatitis viruses, which was identified by the organization experts of the Beijing municipal health administration, awarded the application result with the second prize of the second grade, named as "84" hepatitis decontamination solution, and then named as "84" disinfectant solution. 84 the main component of the disinfectant is sodium hypochlorite (NaClO); the main action mode of sodium hypochlorite disinfection and sterilization is that hypochlorous acid is formed through the hydrolysis of the sodium hypochlorite, the hypochlorous acid is further decomposed to form nascent oxygen, and the protein of thalli and viruses is denatured by the strong oxidizability of the nascent oxygen, so that pathogenic microorganisms are killed. According to chemical measurement, the hydrolysis of sodium hypochlorite is influenced by pH value, when the pH value is over 9.5, the generation of hypochlorous acid is not favorable, and for the sodium hypochlorite with ppm concentration, the sodium hypochlorite is almost completely hydrolyzed into hypochlorous acid in water, and the efficiency is higher than 99.99%. Secondly, hypochlorous acid can act on cell walls and virus shells in the sterilization and virus killing processes, has small molecules and no electric charge, can permeate into the bodies of bacteria (viruses) to carry out oxidation reaction with protein, nucleic acid, enzyme and the like of the bacteria (viruses) or destroy the phosphate dehydrogenase of the bacteria (viruses), leads the sugar metabolism to be disordered and leads the cells to be dead, thereby killing pathogenic microorganisms, particularly killing carcinogen aflatoxin and the like, and the efficiency is higher than 99.99 percent; compared with the traditional high-temperature sterilization at 200-; in order to better guide the production and use of chlorine disinfectant, the state has come out of a plurality of use specifications, such as: GB27952-2011, GB/T14930-2012 and the like.
The existing chlorine test solution adopts the traditional test paper, changes the color of the test paper by chemical reaction through the colorimetric principle, and estimates the test result by comparing the test result with the color on the test paper package; in general, 1. the test paper cannot be stored for too long, so that the test paper is worried about chemical reaction with air; 2. the test paper cannot be exposed in the air, otherwise, the test paper also generates chemical reaction in the air to destroy the original characteristics of the test paper; 3. the reference color on the package can change color after a long time; 4. the color will change with the light and it is not easy to distinguish the exact value. Based on the characteristics, the test paper cannot obtain a high-precision test result, and the precision is usually about +/-50%; and the test paper can only be used once, can not be recycled, and has high use cost.
The existing chlorine test products are indicated to be prepared by water and disinfectant according to the proportion of 1:9, 1:29 and the like, but different diluents: the composition of water is different, and the contained elements are different, which actually influences the calculated result, even if the operation can be performed according to the flow and the specification, the flow is complicated, and the implementation is not easy. In reality, the preparation cannot be well prepared.
The existing chlorine testing products indicate that vegetables, fruits, tableware and fabrics which are put in the disinfectant are necessarily and thoroughly washed clean by clean water, but the prior chlorine testing products do not indicate how to wash the vegetables, the fruits, the tableware and the fabrics, and have no corresponding detection means to display results; the method is a good disinfection method originally, and due to the fact that a preparation method and a detection means are not good, consumers worry that the method cannot be well controlled to use and dare to be used for disinfecting vegetables, fruits, tableware and the like easily.

In order to ensure that the factory calibration value does not change after the user calibration, the data of the user calibration module and the factory calibration module are adjusted through a correction algorithm, and the initial value of the user calibration is set to be i and the initial value of the factory calibration is set to be j (theoretically j > i). Then after user calibration, at test time:
when the test value Y is(user)<j is, Y(actual results)＝(SinX-i)*(j/(j-i))；
When the test value Y is(user)When j is not less than j, the value Y is obtained(actual results)(SinX) × SinX/(SinX + i). The operation process is carried out by an operation module in the circuit board. Taking the chlorine test solution prepared by 12PPM water as an example, the test results of the chlorine test solution test data are shown in Table 3.
TABLE 3
Referring to the data in Table 3, the actual theoretical value of the deviation of the test value is large, and the test value is calibrated by the user, corrected and calculated, and then subjected to
The actual result that display screen 2 shows is comparatively close actual theoretical value, effectively promotes the test accuracy. The user can allocate out the chlorine antiseptic solution of regulation with electron digital display chlorine tester, and the resolution of test is high, and the user accomplishes disinfection work back with standard antiseptic solution, then washs with clear water, can just help the user to inspect through the value of the volume of remaining of test rinsing aquatic after the washing whether thorough sanitization completely, guarantees that the test is thoroughly implemented completely. The testing principle is ingenious in design, dilution water of different regions and different water sources is calibrated in a user calibration mode, and then a real numerical value can be accurately tested through the mixed chlorine testing solution, so that the testing accuracy is guaranteed. If different dilution water is used for diluting the chlorine test solution, the j value in the memory in the electronic digital display chlorine tester can be removed only by pressing the cleaning function key in the control key 3 once, and the setting is restored to the factory initial value; at this moment, the user only needs to carry out user calibration once again, just can used repeatedly, and is simple to use, convenient.
