PH detection device and method

Abstract

The invention belongs to the field of pH detection and particularly relates to a pH detection device and a method. The pH detection device comprises a probe, a detection bracket, a stirrer, a probe purifying mechanism, a probe driving mechanism and a control device, wherein the probe is used for detecting pH of a liquid in a reagent bottle; the detection bracket is used for fixing the probe; the stirrer is used for stirring the liquid in the reagent bottle; the probe purifying mechanism is used for cleaning and air-drying the probe after pH detection; the probe driving mechanism is used for driving the detection bracket to rotate and move vertically to enable the probe to move back and forth in the reagent bottle on the stirrer and in the probe purifying mechanism; the control device is connected with an output end of the probe and a controlled end of the probe driving mechanism. The pH detection device has the following advantages: the probe is purified by the probe purifying mechanism, preparation is made for next experiment, and mechanical technique support is provided for automatic pH detection on the basis of the prior art.

Description

technical field [0001] The invention relates to the field of pH value detection, in particular to a pH value detection device and method. Background technique [0002] There are many ways to measure the PH value of liquids in daily life. For example, various PH reagents will make different color changes according to different pH values, but they cannot accurately test their values; reuse. [0003] In the prior art, there are electronic devices for pH value detection that can be reused and can clearly display specific values, and are simple in structure, cheap, and easy to carry. However, there is a lack of automatic pH value detection devices in the prior art. Since it is an automatic detection and requires repeated use, the cleaning of the electronic equipment for pH value detection is also a technical problem that needs to be solved. Contents of the invention [0004] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides...
