Definition and classification of humidity sensor probes and pH meters
PH meter is a commonly used instrument and equipment. It is mainly used to accurately measure the pH value of liquid media. When paired with the corresponding ion selective electrode, it can also measure the ion electrode potential MV value. It is widely used in industry, agriculture, scientific research, environmental protection and other fields. . This instrument is also a necessary inspection equipment for QS and HACCP certification in food factories and drinking water plants.
According to the needs of production and life, people have scientifically researched and produced many types of acidimeters: 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 accuracy.
According to instrument volume
There are 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 (mini-type) and portable pH meters are generally brought to on-site testing by test personnel.
Choosing the accuracy level of a pH meter is determined based on the accuracy required for user measurement, and then various shapes of pH meters are selected based on user convenience.
◆According to portability, it is divided into: portable pH meter, desktop pH meter and pen-type pH meter.
◆Divided according to use: laboratory pH meter, industrial online pH meter, etc.
◆According to the degree of 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.
◆Pen-type pH meters are generally made with a single range and a narrow measurement range. They are special and simple instruments.
Portable and desktop pH meters have a wide measuring range and are commonly used instruments. The difference is that the portable ones use DC power supply and can be carried to the site. Laboratory pH meters have a wide measurement range, multiple functions, and high measurement accuracy.
The characteristics of industrial pH meters include good stability, reliable operation, certain measurement accuracy, strong environmental adaptability, strong anti-interference ability, analog output, digital communication, upper and lower limit alarm and control functions, etc.
