Technical field
This utility model relates to the detecting device of the rapid and accurate determination solution ph that a kind of pH value detecting device, particularly a kind of scalable rotate.
Background technology
PH value is the parameter often measured in various chemical industry measurement, at present, when pH value measures, the measurement accuracy of pH value is being required be not in extra high situation, commonly used pH reagent paper.Generally, pH reagent paper trisection or the quartering are placed in surface plate, dip a small amount of drop to be measured to pH reagent paper center with Glass rod, after reaction, with the color phase comparison of standard color comparison card, it is possible to judge the pH value measuring liquid.But this situation is often that pH reagent paper is placed on surface plate or other containers, and pH reagent paper is exposed in outside air, easily contaminated, clean surface plate after reading the pH value of liquid more complicated every time.And need to regulate pH value of solution at great majority and carry out observation experiment progress to a certain experiment determining value generally requires the pH value repeatedly measuring solution in the short time, owing to contrasting washing drying receptacle complex operation every time, inefficiency, often miss optimum reacting time, experiment cannot be normally carried out, this with regard to exigence is a kind of can the detecting device of the multiple pH value of one-shot measurement in the short time.
Utility model content
In order to solve not easily to measure in the pH Test paper short time of the prior art the problem of multiple sample and complex operation, this utility model provides the flat board porous pit pH value detecting device of a kind of clean, colorimetric a kind of rotatable adjustment accurately efficient, easy to use, safe.
The technical solution that this utility model is taked is:
The flat board porous pit pH value detecting device of a kind of rotatable adjustment, including a cup dolly (1), 12 circle hole grooves (2), a disk (3), 14 pH standard colorimetric draw-in groove (4), a rotary switch (5) and a switch chassis (6).Wherein 12 circle hole grooves are evenly distributed on cup dolly and constitute reagent paper rest area, disk is provided with 14 equally distributed pH standard colorimetric draw-in grooves, rotary switch is positioned in switch chassis and disk collectively forms and compares zone, reagent paper rest area is connected with coincideing than zone ground, can separate voluntarily, reagent paper rest area and collectively form whole detecting device than zone.
PH reagent paper trisection or the quartering are placed in the circle hole groove on cup dolly, with Glass rod by the pH reagent paper center in a small amount of drop to be measured to circle hole groove, after variable color, by regulating rotary switch, color after changing according to reagent paper quickly searches the pH value that colorimetric card color is corresponding on standard color comparison card, reduce the external environment impact on reagent paper, measure pH value accurately.
Owing to arranging 12 circle hole grooves, therefore can once measure the pH value of multiple sample in the short time, reduce the unnecessary measurement time, it is ensured that experiment is smoothed out.
Disk arranges 14 equally spaced pH standard colorimetric draw-in grooves, is suitable for different sensitivity level required standard colorimetric card.Standard color comparison card is inserted in draw-in groove and standard color comparison card can be prevented contaminated and the long-time recycled for multiple times of energy.
Disk can separate with cup dolly, can realizing self disassembling, simple to operate, the convenient circle hole groove cleaned after using, safety is clean.
Compared with prior art, the flat board porous pit pH value detecting device of a kind of rotatable adjustment of the present utility model is used, it is possible to the pH value of the multiple solution of Accurate Determining in the short time.The simple, convenient cleaning of this device, efficiency is high, it is safer to use, and is the pH value detecting device that a kind of generalization is stronger.
