What are the instruments of water quality analyzer?

There are many kinds of water quality analysis instruments, mainly depending on what functions are needed.

For example:

Multi-spectral on-line water quality analyzer: A comprehensive water quality analyzer integrating various measuring factors, specially developed for surface water and sewage in the field of environmental protection. Based on the principle of UV-Vis absorption spectrum, a special optical path structure is designed inside.

Pollution density index (SDI) water quality on-line analyzer: Pollution density index refers to the parameter value (blocking rate) calculated by the flow attenuation of water samples filtered by 0.45 microporous membrane under the pressure of 0.207MPA in a certain period of time. The performance of filtration system or reverse osmosis system is characterized by monitoring suspended solids in water. It is mainly used for the determination of SDI (pollution index) value in reverse osmosis system.

Flowing current tester: it provides detection, recording and control functions for coagulation process, and is the only best online instrument to directly measure the effect of coagulation dosing.

On-line corrosion rate and water quality analyzer: Corrosion detection is an important part of equipment corrosion protection in operation, which can be divided into two categories: First, in the actual environment, the information of equipment corrosion process is obtained by tracking the corrosion behavior of metal surface, which is called corrosion on-line monitoring. The second is the corrosion result obtained by testing the components of the equipment after the equipment has been running for a period of time, which is called off-line detection corrosion.

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