Handheld water quality testerThe operation steps usually include several key stages such as preparation, instrument calibration, sampling and measurement, data processing, and instrument cleaning. Here is a detailed step-by-step guide:

1、 Preparation stage

1. Ensure that the instrument is fully charged: Before starting the measurement, ensure that the battery of the handheld water quality tester is fully charged to successfully complete the testing process.

2. Preparation of reagents: Prepare the corresponding reagents according to the required measurement parameters (such as residual chlorine, total chlorine, effective chlorine, ammonia nitrogen, dissolved oxygen, etc.) in advance according to the instructions, and ensure that the reagents are within their expiration date.

3. Prepare water sample: Take an appropriate amount of water sample from the water source to be tested, usually 10 milliliters, and pour it into a clean and dry colorimetric bottle. Be careful to avoid the influence of external pollution on the test results.

2、 Calibration instrument

1. Start the instrument: Turn on the power switch of the handheld water quality tester.

2. Select calibration mode: Select the corresponding calibration mode based on the required measurement parameters.

3. Calibration: Use calibration solution to calibrate the instrument and follow the steps in the instrument manual or instruction manual. Calibration is an important step in ensuring the accuracy of measurement results.

3、 Sampling and Measurement

1. Input sample information: PartialHandheld water quality testerAllow input of sample information, such as sampling location, time, etc., to facilitate data management.

2. Wipe the colorimetric bottle: Use a clean mirror cloth to wipe the outer wall of the colorimetric bottle, ensuring that there are no fingerprints or water stains on the surface of the bottle to avoid affecting the accuracy of optical detection.

3. Preliminary measurement: Place the colorimetric bottle into the detection slot of the instrument, cover the instrument lid, and click OK to start preliminary measurement. The instrument will perform basic measurements on the water sample, providing reference data for subsequent detection after adding reagents.

4. Add reagents: According to the selected measurement parameters, add the corresponding detection reagents to the colorimetric bottle. Ensure that the reagents are thoroughly mixed with the water sample and allowed to stand for a period of time. After the reagents have reacted sufficiently, the color of the sample will change.

5. Secondary measurement: Put the colorimetric bottle that has already reacted back into the testing instrument, cover the instrument lid, and click OK to start the secondary measurement. The instrument will accurately calculate the concentration of the target substance in the water sample based on the color change of the water sample in the colorimetric bottle.

4、 Data processing

1. Reading results: After the measurement is completed, read the measurement results directly from the display screen of the measuring instrument.

2. Save data: If the measuring instrument has data storage function, the measurement results can be saved in the instrument or exported through the interface according to the instructions. Some instruments also support uploading detection data to cloud platforms for further analysis and management.

5、 Instrument cleaning

1. Cleaning the instrument: After use, promptly clean the sensors and other parts of the instrument with clean water to avoid residual impurities affecting the accuracy of the next use.

2. Maintenance: Regularly maintain the instrument, such as replacing sensors, batteries, etc., to extend its service life.

Precautions

During the operation, please cover the color bottle lid to prevent liquid from flowing into the detection tank and damaging the instrument.

2. The surface of the colorimetric bottle is smooth, please be sure to wipe it clean during testing, otherwise the test results may be inaccurate.

3. Conduct measurements under stable and suitable environmental conditions as much as possible to reduce interference from external factors.

4. Record in detail the time, location, and results of each measurement for future data analysis and management.

By following the above steps and precautions, it can be ensured thatHandheld water quality testerThe accuracy and reliability provide strong support for water quality monitoring work.
