Description

Technical Field

[0001] The utility model relates to the technical field of pH detection, in particular to a device for detecting pH of a laboratory environment. Background Art

[0002] At present, due to the limitation of laboratory space, many laboratories use multiple experiments in the same experimental unit. For experiments with a greater impact on pH, inaccuracy of experimental results will be caused. For example, in the detection process of all elements in soil, the sample needs to be nitrified, and strong acid will be used in the nitrification process. Therefore, if the samples such as cation exchange capacity, effective state, and pH are tested in the same space, the impact will be greater. However, if each project uses a separate laboratory, the number of production sites is far from enough due to space limitations. In addition, laboratories often need to use inorganic acids such as hydrochloric acid and nitric acid to treat samples. Acidic gases are not easy to diffuse. Excessive air acidity not only affects human health but also corrodes precision instrument and equipment components. Therefore, it is particularly important to detect and control the pH of the laboratory environment. Therefore, the utility model proposes a laboratory environment pH detection device to solve the above problems. Utility Model Content
