The relationship and differences between an ion meter, a pH meter, and an acidity meter
Acidity refers to the definition of the total pH value of substances that can neutralize strong bases in water: PH=-lg{H+} 1. The greater the value of acidity, the stronger the acidity of the solution. 2. No matter at any temperature, neutral The neutral solution AG is always 0. The difference is that 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.
The acidity meter is a commonly used instrument and equipment, mainly used to precisely measure the pH value of the liquid medium, coupled with the corresponding ion selective electrode can also measure the MV value of the ion electrode potential, widely used in industry, agriculture, scientific research, environmental protection and other fields. A pH meter is an instrument for measuring the pH of a solution. The body of the pH meter is a precision potentiometer. When measuring, insert the compound electrode into the solution to be tested. Different electromotive forces will be generated due to the different acidity (hydrogen ion concentration) of the solution to be tested. It will be amplified by a DC amplifier, and finally the reading indicator (voltmeter) will point out the measured solution. pH value. The acidity meter can be used within the range of 0-14pH.
There are many types of acidity meters, such as desktop, portable, and gauge, and there are two types of reading indicators: digital and pointer.
The PH meter is a commonly used instrument and equipment, mainly used to precisely measure the pH value of the liquid medium. It can also measure the MV value of the ion electrode potential with the corresponding ion selective electrode. It is widely used in industry, agriculture, scientific research, environmental protection and other fields.
Classification of pH meter:
According to the needs of production and life, people have scientifically researched and produced many types of pH meters: According to the measurement accuracy, it can be divided into 0.2 level, 0.1 level, 0.01 level or higher precision.
According to the size of the instrument, 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.
