MS-PS type split type ammonia concentration online detectorAmmonia water (NH ∝ [aq]) refers to an aqueous solution of ammonia gas, which has a strong pungent odor and weak alkalinity. In ammonia water, ammonia molecules undergo weak hydrolysis to generate hydroxide ions and ammonium ions. The ionization of ammonia in water can be expressed as the reaction equilibrium constant Kb=1.8 × 10 ^ -5. The pH value of 1M ammonia water is 11.63, and approximately 0.42% of NH3 is converted to NH4 ⁺. Ammonia water is a commonly used source of ammonia in laboratories. It can react with solutions containing copper (II) ions to form deep blue complexes, and can also be used to prepare analytical chemical reagents such as silver ammonia solutions.

Ammonia water, as a type of aqueous solution with Du, has certain irritants and corrosives to the eyes, nose, and skin of the human body, so it is generally used in agricultural supplies such as fertilizers. Ammonia water can not only be used in fertilizers, but also in the production of various iron salts. In industrial fields such as printing and dyeing, wool spinning, etc., ammonia water can dissolve and adjust the acidity and alkalinity, and can be used as a dyeing aid. In the field of organic industry, ammonia water can be used as a catalyst for producing thermosetting phenolic resins. There are many other functions of ammonia water, such as neutralizing agents, detergents, alkaloid extractants, etc., all of which require ammonia water to be prepared.

In military applications, ammonia water can be used as an alkaline disinfectant, with a commonly used concentration of 10% dilute ammonia water (density 0.960), and a concentration of 20% used in winter. In medicine, dilute ammonia water reflexively stimulates respiration and circulation, treats fainting and fainting, and is used as a skin irritant and disinfectant. Ammonia water can also be used in the pharmaceutical industry, gauze mask industry, photo exposure and other fields.

MS-PS type split type ammonia concentration online detector The refractive index of an ammonia solution is measured using the principle of refraction, and there is a good correlation between the refractive index and the concentration of the ammonia solution. Obtain the actual concentration of ammonia water through conversion. This measurement principle has good stability and high accuracy, and is suitable for pipeline installation or container wall installation, as well as other installation methods; The instrument has a compact structure and is easy to operate; 24-hour real-time online monitoring of ammonia concentration; It has factory linear calibration and automatic temperature compensation functions, and has online prism automatic cleaning function. Through online continuous testing, there is no longer a need for frequent manual sampling and laboratory testing, saving a lot of manpower and financial resources, eliminating manual testing errors, ensuring the reliability of ammonia concentration, and improving automation. Relevant concentration data can be remotely transmitted to PLC/DCS/frequency converter for monitoring or control through 4-20mA signals.
