Optical Probes for BOD YSI ProOBOD

YSI ProDSS Smart Sensors – Maximum Precision in Water Quality Monitoring

Digital smart sensors for multiparameter environmental monitoring

The YSI ProDSS Smart Sensors provide accurate and reliable measurements of key water quality parameters. Each sensor is digital, stores its calibration, and is automatically recognized by the ProDSS instrument, ensuring efficiency and accuracy in both field and laboratory applications.

Key Features

• Smart Connectivity: Sensors are automatically recognized by the ProDSS instrument.
• Calibration Storage: Each sensor retains its internal calibration data.
• High Accuracy: Designed with the precision required for scientific studies and environmental monitoring.
• Wide Range of Parameters: Turbidity, dissolved oxygen, pH, ORP, nutrients, conductivity, temperature, and more.
• Freshwater and Saltwater Applications: Specific options for different environments.
• Direct Integration: Fully compatible with the YSI ProDSS multiparameter system.
