Definition and classification of humidity sensor probe and pH meter
PH meter is a commonly used instrument and equipment. It is mainly used to precisely measure the pH value of liquid medium. It can also measure the MV value of ion electrode potential with the corresponding ion selective electrode. It is widely used in industry, agriculture, scientific research, environmental protection and other fields. . The instrument is also an essential inspection equipment for QS and HACCP certification in food factories and drinking water factories.
According to the needs of production and life, people have scientifically researched and produced many types of acidity meters: humidity sensor probe, , stainless steel electric heating tube PT100 sensor, cast aluminum heater, heating coil, fluid solenoid valve
According to measurement accuracy
It can be divided into 0.2 level, 0.1 level, 0.01 level or higher precision.
By instrument volume
There are pen type (mini type), portable type, desktop type and online type for 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 can be divided into: portable pH meter, desktop pH meter and pen pH meter.
◆According to the purpose, it is 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 with 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.
