Tips for using water quality monitoring
Mar 06, 2025| Tips for using water quality monitoring include the following aspects:
Calibrate instruments regularly: Ensure the accuracy of water quality detectors, use calibration fluid for regular calibration, reduce instrument errors, and ensure the accuracy of test results
Standardize sample collection: When collecting water samples, use clean sampling containers to avoid direct contact with water samples with your hands, and ensure that samples are collected in the same time period to reduce detection errors caused by container contamination and time differences.
Prevent sample contamination: During the test process, ensure the cleanliness of the testing instruments and sampling equipment, avoid contacting water samples with unclean hands or tools, and pay attention to avoid the impact of environmental factors such as high temperature and high humidity on the samples.
In-depth understanding of the operating guide: Carefully read and understand the contents of the equipment manual, including the calibration method of the instrument, sample collection and processing steps, etc., to avoid detection errors caused by misunderstandings or misoperation.
Record and analyze data: Establish a water quality test record book to record in detail the time, location, instrument model, and test results of each test, so as to better track the trend of water quality changes. Regularly compare the test data at different times to determine the water quality and take timely measures.
Use TDS water quality test pen: TDS water quality test pen can simply self-test water hardness and water-soluble content. The lower the displayed TDS value, the less soluble solids there are in the water and the purer the water quality.
Direct observation method: Preliminary judgment of water quality by observing suspended impurities and color changes in water samples. After the water sample is left to stand, observe whether there are sediments and color changes, and smell whether there is any odor to judge the purity of the water quality.
Tea brewing test method: After brewing tea with tap water, observe the color change of the tea. If the tea turns black, it means that the iron and manganese content in the water exceeds the standard.
Scale detection method: Check whether there is obvious scale on the inner wall of the kettle and water heater to determine whether the content of calcium, magnesium salts, etc. in the water is too high.
