The difference and connection between pH meter, acidity meter and ion meter
PH meter is a commonly used instrument and equipment, mainly used to precisely measure the pH value of liquid media. A typical pH meter is connected to a voltmeter by a special measuring probe (glass electrode) to measure and display pH readings. Widely used in industry, agriculture, scientific research, environmental protection and other fields. The instrument is also an essential inspection equipment for QS and HACCP certification in food factories and drinking water factories.
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, and different electromotive forces will be generated due to the different acidity (hydrogen ion concentration) of the solution to be tested, which will be amplified by a DC amplifier, and finally the reading indicator (voltmeter) will point out the measured electromotive force. The pH of the solution.
The ion meter is an electrochemical instrument used to measure the concentration of ions in aqueous solution. It uses blue backlight and double-row digital display liquid crystal, which can display pX value and temperature value at the same time. It is suitable for laboratory sampling and determination of various ion concentrations in aqueous solutions in universities, research institutes, environmental monitoring, industrial and mining enterprises and other departments.
the difference
Acidity refers to the ability of the sample to neutralize the alkaline solution, and the 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. To measure different types of samples, it is necessary to choose a suitable pH electrode.
The error of pH meter measurement comes from the error of pH meter electrode, pH meter host, and pH standard buffer
The display 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
