The calibration of blue-green algae generally uses a two-point calibration.
The specific calibration steps are as follows:
1.
For “zero calibration” we generally use distilled water for calibration. Place the clean and dry
blue-green algae sensor probe in a clean calibration container filled with distilled water. The probe should
be at least 2 cm below the solution and there should be no air bubbles on the mirror surface. When the
AD value in the software interface is stable, click Zero Calibration. Rinse the wiper sensor and calibration
container after calibration is complete.
2.
For “Solution calibration” we need a standard water sample of blue-green algae. There are usually two
standards that can be used: A, phytoplankton water samples of known blue-green algae content, B,
Rhodamine B stain solution.
Remove the probe from the distilled water and wipe it into a calibration container containing a standard
water sample or dye solution. The probe should be at least 2 cm below the solution and there should be no
bubbles on the mirror surface.
When the AD value in the software interface is stable, select “1st point” in “Calibration Point”, then enter
the content of blue green algae in the box on the left, and then click “1st point calibration”.
3.
After calibration is complete, rinse the sensor and calibration container with water and dry.
You can also directly enter the value in the “Correction Parameters” box and click “factor calibration”
and “deviation value calibration” to calibrate the factor and deviation value.
