Calibration instructions
1,Calibration of blue-green algae sensors: The blue-green algae sensor software (see the modbus manual) supports 2-point calibration. The more common environmental research dye, rhodamine B, can be used in sensor calibration.
2,Preparation
3,Use
Rhodamine B shows that the fluorescence intensity is inversely proportional to temperature. Use 100 ppb rhodamine B standard solution. To properly set the sensor to ensure the sensitivity of algae blue-green algae at 20 ° C, enter the calibration value according to the temperature standard corresponding to the table below. (The table below shows algae blue-green algae as a function of temperature approximately equal to 100 ppb rhodamine B)
| Temp, ℃ | cells/ml |
| 26 | 54600 |
| 27 | 52471 |
| 28 | 51376 |
| 29 | 49670 |
| 30 | 47641 |
| 31 | 45276 |
| 32 | 43258 |
| 33 | 40711 |
| 34 | 38905 |
| 35 | 37298 |
| 36 | 34875 |
| 37 | 33370 |
Note: The calibration using rhodamine B standard solution is only an approximate value. To ensure accurate readings, the fluorescence readings obtained on site must be linked to the results obtained from the extraction analysis of the above samples. Yushan used Rhodamine B (Item # 70301027) from Keystone.
Warning: Rhodamine B is listed as a substance that may cause carcinogenesis / induction of organism mutations. Gloves must be worn during operation.
Online blue-green algae sensor with automatic cleaning brush can be automatically cleaned without frequent cleaning.
| Maintenance task | Recommended maintenance frequency |
| Calibrate the sensor (if required by the competent authority) | According to the maintenance schedule required by the competent authority |
| Error | Possible reason | solution |
| The operation interface cannot be connected or the measurement result is not displayed. | Controller and cable connection error | Reconnect controller and cable |
