B4QDDF052AECAE2 Hach BioTector B7000 TOC/TN/TP Analyzer, Hach

The B7000 (No. B4QDDF052AECAE2) is a specialized configuration designed for precision at low concentrations, featuring a 0 - 25 mg/L C/N/P measuring range. By integrating carbon and nutrient analysis into a single unit, this analyzer provides the critical C:N:P ratios necessary for efficient nutrient dosing in wastewater treatment plants. It utilizes Hach’s patented Two-Stage Advanced Oxidation (TSAO) technology, which employs hydroxyl radicals to ensure the complete oxidation of complex organic compounds and nutrients, even in samples containing up to 30% chloride. The system is built for heavy-duty industrial use, featuring large-bore internal tubing to handle soft particulates up to 2 mm without clogging. Housed in a robust enclosure with a high-contrast backlit LCD, this 115V single-stream model ensures 99.86% uptime and provides direct measurements of TOC, TIC, TC, TN, and TP, with the ability to correlate results to COD and BOD.

Advantages

• Three-in-One Monitoring: Provides direct analysis of TOC, TN, and TP in a single analyzer, reducing the need for multiple instruments and simplifying data integration.
• Optimized Nutrient Dosing: Accurate C:N:P ratio data allows operators to decrease chemical usage and related utility costs while protecting biological treatment stages.
• Patented TSAO Technology: Delivers superior oxidation power compared to UV-persulfate or combustion methods, ensuring trusted results in the most challenging samples.
• Exceptional Reliability: Certified 99.86% uptime means critical process information is available when it is needed most, minimizing the risk of fines or reputation damage.
• Low Maintenance Requirements: Designed for a six-month service interval in most applications, requiring only reagent replenishment and basic wear-part replacement twice a year.
• Product Loss Detection: Rapid cycle times (from 10 minutes) enable quick detection of organic spikes, helping plants save valuable product and prevent excessive contamination releases.
