National standard method water quality online analyzer monitoring parameters
The national standard water quality online analyzer finds the error data in the process of analysis and processing, and ultimately ensures the correctness of the water quality analysis test results. The national standard method multi-parameter water quality detector has small size, high degree of automation, automatic calibration, automatic range switching, lack of liquid alarm, fault alarm and other functions, cleaning waste liquid and measuring waste liquid are separated, which greatly reduces waste liquid treatment costs and multiple measurements Modes can be selected: fixed-point mode, interval mode, periodic mode, external trigger mode and other modes.
The amount of reagents is reduced, which saves more costs for operation and maintenance services. Imported photoelectric quantitative devices are reliable and stable;
Strong anti-interference ability, imported cold light source, no light intensity attenuation, life span can reach more than 10 years;
The touch screen adopts a 7-inch industrial-grade touch screen, which adapts to various complex environments and many other advantages;
Automatic detection and automatic cleaning: The national standard method water quality online analyzer can automatically clean the sampling pipeline, the measurement unit, the digestion reaction unit, and the pipeline of the measurement unit;
Few movable parts: modular design/easy to install/easy to maintain; automatic protection of system balance damage is realized. Once the temperature controller fails and the temperature is out of control, the power supply can be automatically cut off to ensure safety.
COD: Chemical Oxygen Demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. Oxygen equivalent of substances (generally organics) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water. In the study of river pollution and the nature of industrial wastewater and the operation and management of wastewater treatment plants, it is an important and fast-determinable organic pollution parameter, often represented by the symbol COD.
Total Phosphorus: Total Phosphorus is the result of determination after the water sample is digested to convert various forms of phosphorus into orthophosphate. It is measured in milligrams of phosphorus per liter of water sample.
Total nitrogen: Total nitrogen, abbreviated as TN, the total nitrogen content in water is one of the important indicators to measure water quality.
Ammonia nitrogen: Ammonia nitrogen refers to nitrogen in the form of free ammonia (NH3) and ammonium ions (NH4+) in water. The nitrogen content of animal organic matter is generally higher than that of plant organic matter. At the same time, the nitrogen-containing organic matter in human and animal feces is very unstable and easily decomposes into ammonia. Therefore, when the content of ammonia nitrogen in water increases, it refers to the compound nitrogen in the form of ammonia or ammonium ions.
