Differences and connections between 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: PH=-lg{H+} 1. The larger the acidity value, the stronger the acidity of the solution. 2. Regardless of the temperature, neutralization The solution AG of a property is always 0. Different from this, it is customary to assume that the pH of a neutral solution at 25 degrees Celsius is 7, and the pH of a neutral solution at other temperatures is not 7. In addition, the value range of acidity AG is R, while the traditional value range of pH is 0 ~14.
Acidometer is a commonly used instrument and equipment. It is mainly used to accurately measure the pH value of liquid media. When paired with a 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. An acidometer is an instrument that measures the pH value of a solution. The main body of the acidometer is a precision potentiometer. During the measurement, the composite electrode is inserted into the solution to be measured. Different electromotive forces are generated due to the different acidity (hydrogen ion concentration) of the solution to be measured. This is amplified by a DC amplifier, and finally the reading indicator (voltmeter) indicates the solution to be measured. pH value. The acidometer can be used within the pH range of 0 to 14.
There are many types of acidimeters, including desktop, portable, and meter types. There are two types of reading indicators: digital and pointer.

Classification of pH meters:
According to the needs of production and life, people have scientifically researched and produced many models of pH meters: according to the measurement accuracy, it can be divided into 0.2 level, 0.1 level, 0.01 level or higher accuracy.
According to the volume of the instrument, it is divided into pen type (mini type), portable, desktop 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 the site for testing by testing personnel. Choosing the accuracy level of the pH meter is determined by the accuracy required for user measurement.
