Relative error of illuminance indication: Use comparative method to calibrate the relative indication error to ensure the accuracy of illuminance measurement.
Light source uniformity: Within the effective measurement range of the clarity detector, adjust the illuminance to about 1klx and measure the illuminance at 10 evenly distributed positions to evaluate the uniformity of the light source.
Light source stability: At the bottom of the instrument, use an illuminance meter to measure 7 times at 0 minutes, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, and 30 minutes to evaluate the stability of the light source.
Timer indication error: Select two calibration points, 15s and 20s, measure 3 times at each point, and take the arithmetic mean as the measurement value for that point to calibrate the accuracy of the timer.

Environmental conditions: The laboratory temperature should be controlled between 15 ℃ and 35 ℃, and the relative humidity should not exceed 85%.
Electromagnetic interference: During the calibration process, there should be no strong electromagnetic interference around and it should be in a dark room to ensure the accuracy of the measurement.

3、 Calibration equipment
Illuminometer: used to measure the relative error of illuminance readings, uniformity of light sources, and stability of light sources.
Stopwatch: used to measure the error of timer readings.
Mobile workbench fixture (used in some cases): used to fix the clarity detector and ensure its stability during calibration.

4、 Calibration steps
Preparation stage: Ensure that the calibration environment meets the standards, prepare the necessary calibration tools and reference materials, such as standard samples with known suspended particle concentrations.
Calibration operation:
Adjusting the optical path: By adjusting the position and direction of the optical path, the signals of two photovoltaic cells are made equal or as close as possible.
Calibration using standard samples: Place the standard sample into the detector, perform calibration operations, and correlate its reading with the concentration of the standard sample.
According to the calibration guidelines provided by the equipment manufacturer or relevant national standards, calibrate the clarity detector for other items.
Record and report: Detailed record of all data during the calibration process and prepare a calibration report. The report should include information such as calibration date, calibration personnel, calibration results, etc.

5、 Calibration cycle and precautions
Calibration cycle: The calibration cycle should be determined based on factors such as equipment usage frequency, equipment importance, and equipment usage environment. High frequency equipment, equipment used in critical processes, and equipment with harsh operating environments require more frequent calibration.
Notes:
When using the clarity tester, it should be placed on a stable workbench to avoid external vibrations and interference.
Avoid placing samples inside the instrument to prevent contamination.
After the measurement is completed, clean the instrument in a timely manner to maintain cleanliness and hygiene.
Regularly train personnel responsible for calibration to improve their calibration skills and awareness.
The quality management department should regularly supervise and inspect the calibration work to ensure that the calibration process is executed correctly.

In summary, the calibration of the clarity detector is an important step in ensuring its accuracy and stability. By following the above calibration items, calibration conditions, calibration equipment, calibration steps, calibration cycles, and precautions, it is possible to ensure that the clarity detector always maintains good performance and accuracy.

Company Background Introduction:

Ze Heng The advantage of Huapu in metrology calibration, verification, and confirmation is that it focuses on providing quality control services for biopharmaceuticals. It is very familiar with some special instruments, and its main team comes from pharmaceutical companies and instrument manufacturers, who are familiar with instrument and GMP regulations. For example, our team has specially developed a fluorescence quantitative PCR instrument calibration device to replace imports, which greatly reduces the cost of fluorescence quantitative/qualitative PCR instrument calibration (far lower than other peers); We have developed an internal calibration protocol for the cell counter; Developed internal calibration procedures for cell recovery instruments; The calibration procedure of gel electrophoresis scanner was developed; We have developed integrated wireless probes for lower and higher temperatures required for temperature verification, reducing the cost of users using probes extensively and replacing imports; There are many more examples, as we all come from a biological background, we pay attention to the process requirements of every biological user, focus on biopharmaceutical instruments and equipment, and strive to "go with quality and do instrument and equipment quality control" in order to make biopharmaceuticals safer.

We work closely with other units in terms of services, including mandatory inspections, special inspections, or services that cannot be done, to help customers send and collect items on their behalf, saving time, effort, and convenience.
