The OBS501 is commonly used for measuring turbidity and suspended solids in natural water bodies, wastewater, and industrial effluents. It is ideal for environmental monitoring and water treatment processes.
Ensure the sensor is mounted securely in the water body at a representative depth. Avoid placing it near the bottom to prevent sediment interference. Use a suitable deployment frame or mounting bracket for stability.
Check the connections and cables for any signs of damage or loose fittings. Verify that the data logger or controller is configured correctly. Consult the user manual for specific troubleshooting steps related to connectivity.
Regularly clean the optical surface using a soft, non-abrasive cloth and mild detergent. Inspect the sensor for any damage or wear. Periodically calibrate the sensor as per the manufacturer's guidelines to ensure accuracy.
Follow the calibration procedure outlined in the user manual, which typically involves using standard turbidity solutions. Ensure the sensor is clean and free of debris before calibration.
Yes, the OBS501 is designed to operate in both freshwater and saltwater environments, but regular maintenance and cleaning are essential to prevent biofouling and corrosion.
Check for any obstructions or debris on the sensor's optical surface. Ensure there are no bubbles trapped near the sensor. Re-calibrate the sensor if necessary.
Use antifouling coatings or sleeves to protect the sensor. Regularly clean the sensor and consider using a mechanical wiper if available. Deploy the sensor in a location with minimal biofouling activity if possible.
The OBS501 offers both analog and digital outputs, allowing integration with a wide range of data loggers and monitoring systems. It supports SDI-12 and RS-232 protocols for digital communication.
Use the alignment markings on the sensor and mounting hardware to ensure it is positioned correctly relative to the water flow. This helps in obtaining accurate and consistent measurements.
