Abstract

The invention relates to the field of pH meters, in particular to an intelligent monitoring pH meter which comprises a pH meter body, a cleaning cylinder and cleaning assemblies. The cleaning cylinder sleeves the outer side of a measuring electrode; a supporting plate a is arranged on the peripheral wall of the cleaning cylinder, and a pull ring is arranged on the supporting plate a; a hook is arranged at the bottom of the pull rope a and hung on the pull ring, and the top of the pull rope a is wound on the supporting rod a; a supporting rod a is rotationally arranged between the two sets of fixing blocks, a limiting ring a is arranged on the supporting rod a, and the supporting rod a is sleeved with a torsional spring; a piston is arranged in the box body and provided with a supporting rod b; the supporting rod b is sleeved with the spring; the sliding block is slidably arranged on the outer wall of the box body; one end of the pull rope b is connected with the bottom of the supporting plate c, and the other end of the pull rope b is wound on the supporting rod a; the inner cavity of the box body communicates with the inner cavity of the cleaning cylinder through a hose. There are two cleaning assemblies. According to the invention, the calibration operation is convenient and fast, the measuring electrode cleaning operation is simple, and the cleaning effect is good.

Description

technical field [0001] The invention relates to the field of pH meters, in particular to an intelligent monitoring pH meter. Background technique [0002] A pH meter refers to an instrument used to measure the pH value of a solution. The measuring electrode of the pH meter needs to be cleaned before use to ensure the accuracy of the test. The cleaning of the existing pH meter electrodes is troublesome and needs to be manually cleaned with a special cleaning solution. Then rinse off the cleaning solution with water, and finally have to be dried before use. The cleaning process takes a long time. In addition, the pH meter also needs to be calibrated regularly. During calibration, the standard solutions with pH of 4.01 and 9.18 are prepared, and then the electrodes are inserted into the standard solutions respectively, and the positioning adjustment screw and the slope adjustment screw are turned according to the displayed values ​​to perform calibration, which is inconvenient ...
