PH meter "family"

PH meter is also known as acidity meter, etc., which is a commonly used instrument. It is mainly used to measure the pH value of liquid media, and is widely used in environmental protection, sewage treatment, scientific research, pharmaceutical, fermentation, chemical industry, aquaculture, tap water and other fields. According to the actual application, it has many classifications. Let's take a look at its "big family" together. 

According to the application, it can be divided into pen type, portable, laboratory and industrial type.

(1) The pen-type pH meter is mainly used to replace the function of pH test paper and is easy to use.

(2) Portable is mainly used for field measurement, requiring high precision and perfect functions.

(3) The laboratory is a desktop high-precision analytical instrument that requires high precision and complete functions, including print output, data processing, etc.

(4) Industry is used for continuous measurement of industrial processes. It should not only have measurement display functions, but also alarm and control functions, as well as installation, cleaning, anti-interference and other issues.

According to the type of components, they can be divided into transistor type, integrated circuit type and single chip type. More importantly, the application of microcomputer chips greatly reduces the instrument size and single-chip cost.

According to the classification of the accuracy of the PH meter, it can be divided into 0.2, 0.1, 0.05 and 0.01 grades. The smaller the number, the higher the precision.

According to the reading instructions, it can be divided into pointer type and digital display type. The pointer type is rarely used, but pointer instruments can display the continuous process of data changes, so they are still used in titration analysis.
