NP5800 Total Phosphorus Online Water Quality Automatic Analyzer Hach

Hach NP5800 Total Phosphorus Online Water Quality Automatic Analyzer

Measurement Principle:

The Total Phosphorus Online Automatic Analyzer is based on the ammonium molybdate spectrophotometric method to determine total phosphorus (TP) in water samples. The instrument strictly complies with current standards HJ/T 103-2003 "Technical Requirements for Total Phosphorus Water Quality Automatic Analyzers," HJC-ZY97-2022 "Operation Guide for Testing Total Phosphorus Automatic Water Quality Monitors," and HJ 35X-2019 "Technical Specifications for Installation/Acceptance/Operation of Online Monitoring Systems for Water Pollution Sources (CODCr, NH3-N, etc.)." The measurement data from the Total Phosphorus Online Analyzer show good agreement with the national standard method GB 11893-89 and Hach total phosphorus pre-prepared reagents, ensuring the accuracy and reliability of monitoring results.

Application Industries:

The Total Phosphorus Online Analyzer is used for pollution source monitoring (including municipal sewage inlets and outlets; industrial wastewater outlets); industrial process water monitoring; surface water monitoring; aquaculture tailwater monitoring; coastal and offshore monitoring, among various other applications.

Instrument Features:

Innovative Technology: Inheriting the practical technology of the NT6800 Total Nitrogen Water Quality Online Automatic Analyzer, it incorporates two utility model technologies to further enhance the accuracy and reliability of water quality analysis. ① One is a digestion heating device for water quality analysis, providing an efficient and stable heating environment for the digestion unit. ② The second involves digestion tubes, related heating devices, and components for water quality analysis, offering reliable support for the digestion unit and ensuring accurate and trustworthy monitoring data.

High Efficiency and Precision: A robust and durable plunger pump combined with an integrated flow path design of a 12-channel rotary valve ensures precise sample introduction. The high-density ceramic valve core is corrosion-resistant and wear-resistant, effectively extending maintenance intervals.

Hach Original Reagents: Uses Hach's original reagent formulations, ensuring stability and durability at room temperature, with raw materials that are easy to prepare.

One-Key Cleaning: A convenient one-key cleaning function enables efficient cleaning of digestion tubes, sample introduction tubes, and storage tubes, leaving them as clean as new.

Intelligent Pre-Diagnosis: Equipped with Hach's advanced Prognosys pre-diagnostic technology and Diagnosis diagnostic technology, significantly improving the efficiency and accuracy of equipment maintenance.
1) The maintenance action sequence function of Hach's online instrument software platform allows on-site creation of diverse maintenance action lists, such as instrument cleaning, reagent灌注, personalized calibration, standard sample retesting, and other common maintenance combinations. With a single click, the instrument automatically executes each action in sequence, greatly enhancing operational efficiency and reducing on-site personnel time.
2) Prognosys Pre-Diagnostic Function: Can indicate upcoming issues on the screen and output via digital interfaces, enabling users to take maintenance measures in advance. The indication information can provide details for planned preventive maintenance and information needed to avoid emergency responses, displayed on the screen as a progress bar percentage for easy user recognition.
3) Diagnosis Self-Diagnostic Function: Automatically completes the diagnosis of the instrument's condition, displays diagnostic results on the screen, allows querying of diagnostic information, and outputs diagnostic information via digital interfaces.
