number only indicates the number of measurement interfaces, which is not equal to the number of actual stored data. For a single measurement, one serial number corresponds to one measurement data. For continuous measurement, one serial number corresponds to multiple measurements in the measurement interface.
shelf life and NIST traceability. The polymer calibration solution of the instrument configuration has a service life of ≥12 months (calculated from the date of manufacture). When using the product, please check the effective date on the bottom of the bottle. d) The instrument has been calibrated at full range before leaving the factory.
Figure 8.3). The screen indicates that the 20 NTU has been calibrated. Press to return to measurement mode as shown in Figure 8.4. If you want to continue to calibrate 100 NTU, place the 100 NTU calibration vial in the sample well and press to calibrate.., repeat the steps until 800 NTU calibration is completed, press to return to measurement mode.
TURBIDI TY ME ASU REMEN T 5.1 Sample Vial Handling a) The instrument is equipped with 6 sample vials, the cap is marked with 1 to 6 , and the bottom of the vial also has the same number. The number of the vial and the cap should be the same, do not mix.
Figure 11.3 Figure 11.2 Figure 11.1 5.5 Notes for Measurement Turbidity measurement is related to many factors and is a complicated analytical measurement, which is related to the design of the instrument as well as many other factors, such as stray light, air bubbles, sample vials and operating techniques.
