Fluorescence Blue Green Algae Sensor,
Blue Green Algae Sensor 12vdc,
DS206 Water Quality Probe
DS206 Fluorescence blue-green algae sensor for water quality monitoring of drinking water sources in pond marine survey
The online blue-green algae sensor uses the principle of fluorescence method, which is more efficient and faster than the traditional manua counting method, and can be monitored in real time online. The senso has better repeatability and stability. With automatic cleaning brush, it can eliminate air bubbles and reduce the impact of contamination on the measurement, make the maintenance cycle longer, and maintain excellen stability for long-term online use It can play an early warning role on algae reproduction.
★ Digital sensor, RS-485 output, support MODBUS
★ With automatic cleaning brush to prevent contamination and eliminate air bubbles
★ Direct measurement, simpler than traditional manual counting method
★ Continuous online monitoring, real-time control of water quality dynamics

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.
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)
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.
