The Difference and Connection between PH Meter, Acid Meter and Ion Meter
PH meter, is a commonly used instrumentation, mainly used for precision measurement of the acidity and alkalinity of the liquid medium, a typical pH meter by a special measuring probe [glass electrode (glass electrode)] connected to a voltmeter, measuring and displaying the pH reading. It is widely used in industry, agriculture, scientific research, environmental protection and other fields. The instrument is also a food factory, drinking water factory QS, HACCP certification in the necessary inspection equipment.
Acidity meter is the instrument to determine the pH value of the solution. The main body of the acidimeter is a precision potentiometer. Determination of the composite electrode inserted in the measured solution, due to the acidity of the solution under test (hydrogen ion concentration) different and produce different electric potential, it will be amplified through the DC amplifier, zui by the readout indicator (voltmeter) pointed out that the pH value of the solution under test.
Ion Meter is an electrochemical instrument used to measure the concentration of ions in aqueous solution, it adopts blue backlight, double rows of digital display liquid crystal, can display pX value and temperature value at the same time. It is suitable for colleges and universities, research institutes, environmental monitoring, industrial and mining enterprises and other departments of the laboratory to take samples to determine the concentration of various ions in aqueous solution.
Difference
Acidity refers to the ability of the sample to carry out neutralisation reaction with alkali solution, and PH value refers to the negative logarithm of the activity of hydrogen ions in the sample solution.
The core technology of PH meter measurement lies in the PH meter electrode, measuring different types of samples need to choose the appropriate PH electrode.
PH meter measurement error comes from the PH meter electrode, PH meter host, PH standard buffer error.
The display value of PH meter after temperature compensation is the PH value under the actual temperature of the sample.
The writing of pH should be pH, not PH.
