Water quality testing instruments are divided into multi parameter measuring instruments and single parameter measuring instruments according to their functions.
Water quality detectors are divided into COD meter, BOD meter, ammonia nitrogen meter, total phosphorus meter, turbidity meter, pH meter, etc. according to the measurement items.
Water quality testing instruments are divided into portable testing instruments, laboratory intelligent testing instruments, simple and economical testing instruments, online testing instruments, etc. according to their usage environment.
Environmental protection is now a very important topic, and water quality safety is also a topic of great concern for citizens. However, in recent years, water ecology has been greatly polluted. For example, in the recently popular Yangtze River Delta region, thousands of pig carcasses were found in the Huangpu River. The specific source and cause of death seem to have not been clarified so far, which is the reason for the inadequate supervision of water quality regulatory authorities. Then came news of poor water quality not far away. The tap water had a strange smell for several consecutive days, and citizens became increasingly sensitive to the safety issues of tap water.
Therefore, we need a water quality detector, which not only allows us to trust the water quality, but also enables us to understand how much sewage can damage the aquatic ecosystem.
A water quality detector is a professional instrument used to analyze the content of water quality components, mainly referring to measuring water quality; In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge for items such as BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, pH, dissolved oxygen, etc., because water quality detection plays an important role in water resources. The general principle of a water quality detector is to involve the corresponding substances in the water through chemical reactions, and then compare the color values through water quality monitoring instruments.
The functions that conventional water quality monitoring instruments should have are:
1. Humanized design, large screen display, and simple operation.
2. It can routinely or quickly measure several measurement indicators and store 12000 sets of measurement data.
3. Multiple measurement methods, including portable, suspended, and laboratory, can be used according to different usage conditions.
4. The instrument is equipped with intelligent timing, intelligent heating, delay protection, and energy saving.
5. Equipped with RS232 serial port, data can be transmitted to the computer.
