DWACAA152AAC2 Hach BioTector B3500dw TOC Analyzer, Hach

The B3500dw (No. DWACAA152AAC2) features Hach’s patented Two-Stage Advanced Oxidation (TSAO) technology, which is officially EPA-approved (Method 10261) for drinking water analysis. Unlike standard UV-based systems, the TSAO process achieves complete oxidation of organic compounds, including those that are typically "invisible" to scanning UV technologies. This specific configuration is a dual-stream (2-stream) system operating on 230V AC, allowing for the simultaneous monitoring of two separate water lines—such as raw influent and treated effluent—to automatically calculate % TOC removal. Housed in a compact, space-saving fiberglass enclosure, the analyzer delivers a 99.86% uptime record. It is capable of measuring Total Organic Carbon (TOC), Total Inorganic Carbon (TIC), and can provide correlated values for BOD and COD, offering a comprehensive view of water quality with minimal footprint.

Advantages

• EPA-Approved Technology: Uses the unique TSAO process, providing a certified and trusted method for regulatory drinking water reporting.
• Dual-Stream Efficiency: Monitors two streams and calculates % TOC removal within a single unit, eliminating the need for multiple analyzers and reducing capital costs.
• Lowest Cost of Ownership: Typically requires reagent replenishment and standard maintenance only twice a year, significantly lower than the bi-weekly requirements of competing systems.
• Rock-Solid Reliability: Engineered for 99.86% uptime with a self-cleaning sample reactor that prevents fouling and ensures consistent data integrity.
• Advanced Source Protection: Capable of detecting organic spikes in source water that UV-based sensors might miss, protecting downstream membrane and filtration systems.
• High Data Capacity: Stores the previous 9,999 reaction data points and 99 fault events, accessible via a high-contrast backlit LCD or digital communication.
