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.
Features
★ 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

Maintenance methods and common problems Maintenance schedule and method
I. Maintenance schedule
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 |
2. Maintenance method Sensor maintenance
- External surface of the sensor: Clean the external surface of the sensor with tap water. If debris remains, wipe it with a moist soft cloth. For some stubborn dirt, you can add some household washing solution to the tap water to clean it.
- Check the cable of the sensor: the cable should not be tightened during normal work, otherwise the internal wires of the cable will be easily broken and the sensor will not work properly.
3) Check whether the measurement window of the sensor is dirty and whether the cleaning brush is normal.
- Check the sensor's cleaning brush for damage.
- 18 months of continuous use, need to return to the factory to replace the dynamic sealing device.

Quality assurance
Our company assures first-hand buyers that there will not be any product defects caused by substandard materials or factory manufacturing within one year from shipment.
Because the sensor has an automatic cleaning brush and a motor, it belongs to a dynamic seal structure. After 18 months of continuous use, the dynamic sealing device needs to be returned to the factory. If the buyer does not return to the factory and the sensor enters the water or fails to work, all consequences caused by the buyer shall be borne by the buyer If a defect is found during the warranty period, it is promised to repair or replace the defective product, or return the payment in addition to the first shipping and related formalities. Any product repaired or replaced during the warranty period will only enjoy the remaining warranty period of the original product.
After receiving the customer's questions about product quality, our company will confirm whether the product needs to be repaired within two weeks; products that have not been
approved for repair cannot be returned.
