There are many classifications of acidity meters, which can be classified from different precisions, and can also be classified from reading index. The environment and component types can still be classified. The following is a brief introduction to the main categories of acidity meters. 512 Slice CT,Heart CT Scanner,CT Scanner Screening,Ge Cardiac CT Scanner MinFound Medical Systems Co., Ltd , https://www.minfoundmed.com
First, the accuracy classification
The ph meter can be divided into 0.2, 0.1, 0.02, 0.01 and 0.001. The smaller the number, the higher the accuracy.
Second, the reading indicator classification
It can be divided into two types: pointer type and digital display type. Pointer pH meters are now rarely used, but pointer meters are capable of displaying continuous changes in data and are therefore used in titration analysis.
Third, component type classification
It can be divided into transistor type, integrated circuit type and single-chip microcomputer type. Now more is the application of microcomputer chip, which greatly reduces the instrument volume and stand-alone cost; but the development cost of the chip is very expensive.
Fourth, according to the environment used
Can be divided into pen PH meter, portable PH meter, laboratory PH meter and industrial PH meter.
The pen type pH meter is mainly used to replace the function of the pH test paper, and has the characteristics of low precision and convenient use. Portable pH meters are mainly used in field and field testing methods, requiring high precision and perfect functions. The laboratory pH meter is a benchtop high-precision analytical instrument that requires high precision and full functionality, including printouts, data processing, and more. Industrial pH meters are used for continuous measurement of industrial processes, not only have measurement display functions, but also alarm and control functions, as well as installation, cleaning, anti-interference and other issues.
