The introduction of water quality analyzer, what instruments are there for water quality analyzer?

A multi-parameter water quality detector is a device used to detect multiple parameters of water quality. The following are several common multi-parameter water quality detectors and their detection parameters: 1

pH meter: used to measure the pH of water quality, which can reflect whether the water body is suitable for biological growth and whether there is pollution. 2.

Conductivity meter: It is used to measure the conductivity of water quality, which can reflect the concentration of ions in the water body, so as to evaluate the purity of water quality. 3.

Dissolved oxygen meter: It is used to measure the dissolved oxygen content in the water, which can reflect the oxygen content in the water body, and is of great significance for evaluating whether the water body is suitable for biological survival. 4.

Turbidity meter: used to measure the turbidity of water quality, which can reflect the content of suspended particles in the water body, and is of great significance for evaluating the cleanliness of the water body. 5.

Residual chlorine meter: used to measure the remaining chlorine content in the water body....

Multi-parameter water quality analyzer, also known as multi-parameter automatic water quality monitoring integrated system, is suitable for: water source monitoring, environmental protection monitoring station, municipal water treatment process, municipal pipe network water quality supervision, rural tap water monitoring; Circulating cooling water, swimming pool water operation management, industrial water recycling, factory aquaculture and other fields. In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge.

The design of the detection point and the quality of the testing instruments (mainly water quality analyzers) play a crucial role in the monitoring of the water environment. The content of various chemical components in water is determined by chemical and physical methods. Water quality analyzers are divided into three types: simple analysis, full analysis and special analysis.

The simple analysis is carried out in the field, and the analysis items are few, but the requirements are fast and timely, and the special analysis projects suitable for the preliminary understanding of the main chemical components of groundwater in each aquifer in a large area are determined according to the needs of the specific task. In addition, the automatic ion analyzer can quickly and accurately analyze qualitative and quantitatively, and can be fully automated, intelligent, real-time, and multi-parameter analysis at the same time.

Water quality analyzers are:

1. Comprehensive indicators of organic matter.

1. BOD tester: direct reading of data, five-day culture method to detect BOD

2. COD tester: used to determine the COD value in clear water samples.

3. Infrared oil tester: used for the determination of petroleum and animal and vegetable oils in groundwater, surface water, industrial wastewater and domestic sewage.

4. Ammonia nitrogen detector: rapid quantitative determination of ammonia nitrogen index.

5. Total phosphorus tester: rapid and quantitative determination of total phosphorus index, if the total phosphorus is too high, it will cause eutrophication of the water body.

6. Total nitrogen tester: to measure the total nitrogen index, when the nitrogen and phosphorus substances in the surface water exceed the standard, microorganisms multiply, plankton grow vigorously, and eutrophication appears.

There are many kinds of water quality analysis instruments, mainly depending on what function you need?

For example: multispectral water quality analyzer: a comprehensive water quality analyzer that integrates multiple measurement factors for surface water and sewage in the field of environmental protection. It is based on the principle of ultraviolet-visible absorption spectroscopy, and the internal design is designed with special hand-excavated optical path structure.

Pollution Density Index (SDI) Water Quality Analyzer** Analyzer: Pollution Density Index, which refers to the parameter value (blocking rate) calculated by the flow attenuation of a water sample under pressure through the microporous filter membrane holding core filtration over a certain period of time. By monitoring the performance of suspended matter in the water, the performance of the filtration system or reverse osmosis system is monitored.

It is mainly used for the determination of SDI (pollution index) value in reverse osmosis system.

Corrosion rate water quality analyzer: Corrosion detection is an important part of equipment corrosion prevention in operation, which can be divided into two categories: First, in the actual environment, the relevant information of the equipment corrosion process is obtained by tracing the corrosion behavior of the metal surface, which is called corrosion monitoring, referred to as monitoring.

The second is the corrosion results obtained by detecting the parts and components of the equipment after a period of operation of the equipment, which is called off-line detection of corrosion, referred to as detection.

There are many water quality analyzers, so I won't give examples one by one, mainly depending on what the water quality analyzer you need is used for.
