产品概述
• SS306-01-ANALOG measures chemical oxygen demand (COD) using dual-wavelength ultraviolet absorption without chemical reagents.
• The integrated self-cleaning system reduces biofouling, with automatic temperature and turbidity compensation for field stability.
• Measured COD data are available through selectable 4–20 mA, 0–5 V or 0–10 V analog outputs for integration with controllers and data-acquisition systems.
