How to correctly distinguish the types of pH meters
1. Classification based on instrument accuracy: pH meters can be divided into 0.2, 0.1, 0.02, 0.01, and 0.001 levels. The smaller the number, the higher the accuracy of the pH meter.
2. Classification based on reading instructions: pH meters can be divided into two types: pointer type and digital display type. Pointer type pH meters are now rarely used.
PH meters, acidity meters, online pH meters, industrial pH meters, industrial online pH meters, Qingdao pH meters, Taiwan Shangtai pH meters, Mettler Toledo pH meters, etc. are professionally supplied by the Qingdao office of Kuangsi Electronics.
3. Classified by component type: pH meters can be divided into transistor type, humidity sensor probe, stainless steel electric heating tube, PT100 sensor, fluid solenoid valve, cast aluminum heater, heating ring
Integrated circuit type and single-chip microcomputer type are now more commonly used with microcomputer chips, greatly reducing the volume and single machine cost of instruments.
4. Classified according to application scenarios: pH meters can be divided into pen type pH meters, portable pH meters, laboratory pH meters, and industrial online pH meters.
The pen type pH meter is mainly used to replace the function of pH test paper, and has the characteristics of low accuracy and convenient use.
Portable pH meters are mainly used for on-site and field measurements, requiring high accuracy.
The laboratory pH meter is a desktop high-precision analytical instrument with high accuracy and full functionality, including printing output, data processing, etc.
Industrial online pH meter is used for continuous measurement of online industrial processes, with measurement display function, alarm and control function, as well as installation, cleaning, anti-interference, etc.
