Water quality testing is very important to the ecological environment, people's livelihood safety, scientific research and development, etc. So what equipment is generally required for water quality testing? The Suke Purchasing Manager learned that to build a water quality testing laboratory, there are really a lot of testing instruments that need to be equipped. Common water quality testing instruments are as follows:

Balance

The balance can be said to be one of the most commonly used measuring instruments in laboratories. Especially the most commonly used electronic balances now have a variety of models, higher accuracy and more comprehensive functions. In addition to weighing, they can also realize counting and density measurement. In the field of water quality testing, the measurement and calculation of some indicators also requires an analytical balance with a precision of 1/10th. Choosing a reliable electronic balance can greatly improve the efficiency of water quality inspection work.

microscope

Microscopes are also one of the most commonly used equipment in laboratories. Divided into optical microscope, electron microscope, polarized light microscope, digital microscope, etc. Generally speaking, a high-power biological microscope is sufficient for water quality testing. Biological microscopes are optical microscopes, with a relatively large magnification, and can observe small bacteria and other substances.

UV spectrophotometer

Ultraviolet spectrophotometer is an analytical instrument based on the principle of ultraviolet-visible spectrophotometry, which uses the radiation absorption of substance molecules in the ultraviolet-visible spectral region for analysis. It is commonly used for qualitative analysis, purity inspection, structural analysis, determination of complex composition and stability constants, reaction kinetics research, etc.

Atomic absorption spectrometer

Atomic absorption spectrometer, also known as atomic absorption spectrophotometer, is used to analyze metal elements based on the effect of atomic vapor in the ground state of the substance on the absorption of characteristic radiation. It can sensitively and reliably determine trace or trace elements. It is widely used in the fields of metallurgy, geology, mining, petroleum, light industry, agriculture, medicine, health, food and environmental monitoring.

Atomic fluorescence photometer

Atomic fluorescence photometer is mainly used for trace analysis of heavy metals arsenic, mercury, selenium, lead, etc. in water quality, food, dairy products, and beverages. The principle is to use potassium borohydride or sodium borohydride as a reducing agent to add The element to be analyzed is reduced to a volatile covalent gaseous hydride (or atomic vapor), which is then introduced into the atomizer with the aid of a carrier gas, and atomized in an argon-hydrogen flame to form ground-state atoms.
