How to Divide a PH Meter
According to measurement accuracy
It can be divided into 0.2 level, 0.1 level, 0.01 level or higher precision.
By instrument volume
It is divided into pen type (mini type), portable type, desktop type and online type for online continuous monitoring and measurement.
According to the requirements of use
Pen type (miniature) and portable pH pH meters are generally used by inspectors to bring them to the site for inspection.
The accuracy level of the pH meter is selected according to the accuracy required by the user for measurement, and then various shapes of pH meters are selected according to the convenience of the user.
According to portability, it is divided into: portable pH meter, desktop pH meter and pen pH meter.
According to the application, it can be divided into: laboratory pH meter, industrial online pH meter, etc.
According to the advanced level, it can be divided into economical pH meter, intelligent pH meter, precision pH meter or pointer pH meter and digital display pH meter.
The pen-type pH meter is generally made into a single range and has a narrow measurement range. It is a special and convenient instrument.
Portable and desktop pH meters have a wide range of measurement and are commonly used instruments. The difference is that the portable is powered by DC and can be carried to the site. The laboratory pH meter has a wide measurement range, multiple functions and high measurement accuracy.
The industrial pH meter is characterized by good stability, reliable operation, certain measurement accuracy, strong environmental adaptability, strong anti-interference ability, and has analog mileage output, digital communication, upper and lower limit alarm and control functions.
