Abstract

The invention belongs to the field of pH detection and particularly relates to a pH detection system and a method. The pH detection system comprises a feed device, a liquid preparation device, a pH detection device, a manipulator device and a control device, wherein the feed device is used for feeding soil to a reagent bottle on a weighing device; the liquid preparation device is used for adding corresponding adaptive liquid to the reagent bottle to form a detection liquid; the pH detection device is used for detecting pH of a to-be-detected liquid; the manipulator device is used for moving the reagent bottle between the devices; the control device is connected with controlled ends of the feed device, the liquid preparation device, the pH detection device and the manipulator device. The pHdetection system has the following advantages: precise soil feeding is realized by the feed device, automatic feeding of the adaptive liquid is realized by the liquid preparation device, a soil mixedsolution is detected automatically by the pH detection device, the reagent bottle is moved between the devices by the manipulator device, and mechanical technique support is provided for automatic pHdetection of solids 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 system 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 the value; another example is PH test paper, which cannot display the specific PH value and cannot be repeated. use. [0003] In the prior art, there is already an electronic device for pH value detection that can be used repeatedly, can clearly display specific values, and is simple in structure, cheap in price, and convenient to carry. For the detection of gases and liquids, a simple pH value detection device can be used directly, but for solids, such as soil, it is necessary to take the amount, add an adapter liquid to form a detection liquid, and then detect the detection liquid. Such devices are lacking....
