2024-03-15
Depending on the analysis method, water quality testing may also involve high-end instruments such as mass spectrometers, nuclear magnetic resonance instruments, and X-ray analyzers. These instruments can provide more accurate and comprehensive water quality data, and provide strong support for water quality assessment and management.
Water quality testing is a complex process involving multiple parameters and indicators, so a variety of different instruments are required. The following are some common water quality testing instruments and their uses:
- Organic comprehensive index detection instrument：
- COD analyzer: used to measure the content of organic matter in water, the more the content, the more serious the pollution.
- BOD analyzer: used to determine biochemical oxygen demand (BOD) in water.
- Ammonia nitrogen detector: used to determine the content of ammonia nitrogen in water, high concentration of ammonia nitrogen is toxic to fish.
- Total phosphorus meter: used to detect the total phosphorus content, too much phosphorus will lead to lake eutrophication, the Gulf red tide.
- Total nitrogen analyzer: used to detect the content of total nitrogen in sewage.
- Physical and chemical and disinfectant index detection instrument：
- PH meter: used to measure the pH of water.
- ORP tester: used to measure the oxidation reduction potential.
- Conductivity meter: used to determine the conductivity of water, reflecting the concentration of ions in water.
- Residual chlorine detector: used to detect the content of residual chlorine in water.
- Suspended solids analyzer: used to determine the content of suspended solids in water.
- Turbidimeter: Used to measure the turbidity of water.
- Dissolved oxygen meter: used to detect the concentration of dissolved oxygen in water samples.
- Industry-specific water quality detector：
- Aquaculture water quality analyzer: suitable for aquaculture water detection, control of water quality standards.
- Swimming pool water quality detector: used to measure the urea in the swimming pool, total chlorine and residual chlorine, PH and turbidity and other parameters.
- Drinking water rapid analyzer: used for the rapid measurement of residual chlorine, total chlorine, chlorine dioxide and ozone in drinking water and its water sources.
- Other commonly used instruments：
- Spectrophotometer: Used for water quality analysis based on absorbance.
- Atomic absorption spectrophotometer: used to determine the content of trace elements in water.
- Gas chromatograph and liquid chromatograph: used for qualitative and quantitative analysis of organic matter.
- X-ray instrument: used for the detection of radioactive substances.
- Analytical balance: for precise weighing of samples and reagents.
- Water Sampler: Used to collect water samples from a body of water for analysis.
In addition, depending on the analysis method, water quality testing may also involve high-end instruments such as mass spectrometers, nuclear magnetic resonance instruments, and X-ray analyzers. These instruments can provide more accurate and comprehensive water quality data, and provide strong support for water quality assessment and management.
It should be noted that different water quality testing projects may require the use of different instruments and reagents, so in actual operation, it is necessary to select appropriate instruments and methods according to specific testing needs and standards. At the same time, the use and maintenance of the instrument also need to follow the corresponding specifications and standards to ensure the accuracy and reliability of the test results.
