The difference and connection between pH meter, acidity meter, and ionization meter
A pH meter is a commonly used instrument mainly used for precise measurement of the pH value of liquid media. A typical pH meter consists of a special measuring probe [glass electrode] connected to a voltmeter to measure and display the pH reading. Widely used in industries, agriculture, scientific research, environmental protection, and other fields. This instrument is also an essential inspection equipment for QS and HACCP certification in food factories and drinking water plants.
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 then the pH value of the measured solution is indicated by a reading indicator (voltmeter).
Ionic meter is an electrochemical instrument used to measure the concentration and content of ions in aqueous solutions. It adopts blue backlight and dual row digital display LCD, which can simultaneously display pX value and temperature value. Suitable for laboratory sampling and determination of various ion concentrations in aqueous solutions in colleges, research institutes, environmental monitoring, industrial and mining enterprises, and other departments.
difference
Acidity refers to the ability of a sample to undergo a neutralization reaction with an alkaline solution, while pH value refers to the negative logarithm of the hydrogen ion activity in the sample solution
The core technology of pH meter measurement lies in the pH meter electrode, and measuring different types of samples requires selecting suitable pH electrodes
The measurement error of the pH meter comes from the errors of the pH meter electrode, pH meter host, and pH standard buffer solution
The displayed value of the pH meter after temperature compensation is the pH value at the actual temperature of the sample
The writing of pH should be pH, not pH
