The invention discloses a PH (potential of hydrogen) adjusting device. The PH adjusting device comprises an adjusting cup, an acid solution cup and an alkali solution cup, the acid solution cup is used for storage of acid solution, and the alkali solution cup is used for storage of alkali solution. A control valve I is arranged on a dropper passage I which is arranged between the acid solution cup and the adjusting cup, a control valve II is arranged on a dropper passage II which is arranged between the alkali solution cup and the adjusting cup, and a PH meter used for measuring a PH value is arranged in the adjusting cup. Since the dropper passage I and the dropper passage II are arranged between the adjusting cup and the acid solution cup and between the adjusting cup and the alkali solution cup respectively and provided with the control valve I and the control valve II respectively, acid solution and alkali solution can be dropwise added into the adjusting cup by the aid of the control valve I and the control valve II, PH value adjustment is realized conveniently, PH value adjustment efficiency can be effectively improved while adjustment precision can be improved as well.
Description
technical field [0001] The invention belongs to the technical field of pH adjustment, in particular to a pH adjustment device. Background technique [0002] With the continuous development of chemical analysis technology, higher requirements are put forward for the accuracy and efficiency of pH adjustment of liquid samples in chemical analysis. At present, when adjusting the pH of a liquid sample, the usual practice is to add the corresponding acid (or alkali) solution to the liquid sample, and monitor the pH of the liquid sample at any time to ensure the accuracy of the results. Although such a pH adjustment device can meet the requirements of use to a certain extent, it has the disadvantages of low adjustment efficiency and inaccurate adjustment. Contents of the invention [0003] In view of this, the object of the present invention is to provide a pH adjustment device, which can not only effectively improve the pH adjustment efficiency, but also improve the adjustment ...
