Differences and Connections Among Acidimeter, 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 acidity value, the stronger the acidity of the solution. 2. At any temperature, a neutral solution AG is always 0. Unlike this, it is customary to assume that the pH of a neutral solution at 25 degrees Celsius is 7, while the pH of a neutral solution at other temperatures is not 7. In addition, the range of acidity AG is R, while the traditional pH range is 0-14
Acidimeter is a commonly used instrument and equipment, mainly used to accurately measure the pH value of liquid media. It can also measure the ion electrode potential MV value when equipped with corresponding ion selective electrodes. It is widely used in industries, agriculture, scientific research, environmental protection and other fields An acidimeter is an instrument used to measure the pH value of a solution. The main body of an 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 acidity (hydrogen ion concentration) of the measured solution. It is amplified by a DC amplifier and finally indicated by a reading indicator (voltmeter) to determine the pH value of the measured solution. The acidity meter can be used within the pH range of 0-14.
There are various types of acidity meters, including desktop, portable, and phenotype. The reading indicator has two types: digital and pointer
PH meter is a commonly used instrument and equipment, mainly used for precise measurement of the pH value of liquid media. It can also measure the ion electrode potential MV value when paired with corresponding ion selective electrodes, and is widely used in industries, agriculture, scientific research, environmental protection, and other fields.
Classification of pH meters:
People have scientifically researched and produced many models of pH meters according to the needs of production and life: they can be classified into 0.2 level, 0.1 level, 0.01 level or higher accuracy according to measurement accuracy.
There are three types of instruments based on their volume: pen type (mini type), portable, desktop, and online continuous monitoring and measurement. According to the usage requirements, pen type (mini) and portable pH meters are generally brought to the site for testing by the testing personnel. The accuracy level of a pH meter is determined based on the user's required measurement accuracy
