The difference between acidity meter, pH meter, and ion meter
Acidity refers to the total amount of substances in water that can neutralize strong bases. The definition of pH value is as follows: pH=- lg {H+} 1. The higher the value of acidity, the stronger the acidity of the solution 2. Regardless of temperature, the AG of a neutral solution is always 0. Unlike this, it is customary to assume that a neutral solution at 25 degrees Celsius has a pH of 7, while the pH of neutral solutions at other temperatures is not 7. In addition, the range of acidity AG is R, while the traditional range of pH is 0-14
Acidity meter is a commonly used instrument and equipment, mainly used to accurately measure the pH value of liquid media. Equipped with corresponding ion selective electrodes, it can also measure the MV value of ion electrode potential. It is widely used in industries, agriculture, scientific research, environmental protection, and other fields. Acidity meter is an instrument for measuring the pH value of solutions. The main body of the acidity meter is a precision potentiometer. When measuring, the composite electrode is inserted into the measured solution, and different electromotive forces are generated due to the different acidity (hydrogen ion concentration) of the measured solution. It is amplified by a DC amplifier, and finally the pH value of the measured solution is indicated by a reading indicator (voltmeter). The acidity meter can be used within the pH range of 0-14.
There are various types of acidity meters, such as desktop, portable, and phenotypic. There are two types of reading indicators: digital and pointer
A pH meter is a commonly used instrument and equipment, mainly used to accurately measure the pH value of liquid media. Coupled with corresponding ion selective electrodes, it can also measure the MV value of ion electrode potential, and is widely used in industries, agriculture, scientific research, environmental protection, and other fields.
Classification of pH pH meters:
According to the needs of production and daily life, people have scientifically researched and produced many types of pH meters: according to measurement accuracy, they can be divided into 0.2, 0.1, 0.01 or higher accuracy levels.
According to the volume of the instrument, there are pen type (mini type), portable, desktop, and online continuous monitoring and measurement online types. According to the requirements for use, pen (mini) and portable pH meters are generally brought to the site for testing by testing personnel. The accuracy level of selecting a pH meter is determined by the accuracy required for user measurement
