Shangtai suntex, Taiwan, China, China, HA405-DPA-SC-S8, PH electrode

PH meter is a commonly used instrument and equipment, mainly used for precise measurement of the pH value of liquid media. It can also measure the ion electrode potential MV value when paired with corresponding ion selective electrodes, and is widely used in industries, agriculture, scientific research, environmental protection, and other fields. This instrument is also a testing equipment for QS and HACCP certification in food factories and drinking water plants.
PH
The hydrogen ion concentration index (refers to the ratio of the total number of hydrogen ions to the total amount of substances in a solution. Its value is commonly known as the "pH" value (pronounced as "/pi'et ∫/" in English and "eit ∫/" in French). The numerical value indicating the degree of acidity or alkalinity of a solution, which is the negative logarithm of the commonly used concentration of hydrogen ions.

To facilitate understanding and explanation of pH, first explain the ionization of water and the ion product constant of water.
Ionization of water: Water is an extremely weak electrolyte that can undergo weak ionization. Its ionization equation is H2O+H2O ≈ H3O++OH -, abbreviated as H2O ≈ H++OH -, which is an endothermic process. The ionization of water is affected by temperature, and adding acid or alkali can suppress the ionization of water. The ionization of water is caused by the interaction between water molecules, making it extremely difficult to occur. It was experimentally measured that only 1 × 10-7mol of water molecules in 1L of pure water undergo ionization at 25 ℃. The number of H+and OH - ionized from water molecules is always equal in any case. At 25 ℃, [H+]=[OH -]=1 × 10-7mol/L in pure water.
The ion product constant of water: [H+] · [OH -]=KW, where KW is called the ion product constant of water, abbreviated as the ion product of water; [H+] and [OH -] respectively refer to the total concentration of hydrogen ions and hydroxide ions in the entire solution. KW only changes with temperature and is a temperature constant. At 25 ℃, [H+]=[OH -]=1 × 10-7mol/L, KW=1 × 10-14; At 100 ℃, [H+]=[OH -]=1 × 10-6mol/L, KW=1 × 10-12.

The PH electrode of HA405-DPA-SC-S8 uses gel reference electrolyte and is pre pressurized to 2.5 bar (36 psi). Internal overpressure ensures that the electrolyte gradually flows out, effectively cleaning the diaphragm and preventing the inflow of process media.
Electricity has a longer operating life
The electrode also comes with a silver ion trap to prevent the membrane from being contaminated in sulfur-containing media, thereby extending the operating life of the electrode.

The pH value of water
PH value is one of the important physicochemical parameters of aqueous solutions. Any natural phenomenon involving aqueous solutions. Chemical changes and production processes are all related to pH value, therefore, pH value measurement is required in industrial, agricultural, medical, environmental protection, and scientific research fields.
The pH value of water is the negative logarithm of the activity of hydrogen ions in water, expressed as:
pH=-lg[H+]
The pH value is sometimes also known as the hydrogen ion index. Due to the small value of hydrogen ion activity, it is inconvenient to use in applications, so the pH value is used

This concept is used as an indicator to determine the acidity and alkalinity of aqueous solutions. Moreover, the negative logarithm of hydrogen ion activity can indicate the magnitude of changes in acidity and alkalinity, making it very convenient to apply and obtain (at 25 ℃):
⑴ Neutral aqueous solution, pH=7
⑵ Acidic aqueous solution, pH<7, the lower the pH value, the stronger the acidity;
⑶ Alkaline aqueous solution, pH>7, the higher the pH value, the stronger the alkalinity.
