WDet-5000TPN Total Nitrogen Water Quality Online Analyzer
WDet-5000TPN is a new self-developed automatic online analyzer for measuring total nitrogen. Based on our patented Permeance Measurement Technology Platform, combined with Xenon Lamp/Grating Spectrograph Technology and Digestion Colorimetric Integration Technology, it can achieve high precision, low detection limit, high stability and low maintenance of automatic TN online monitoring. The product fully meets the application of pollution sources, industrial production process, municipal wastewater, etc. It has passed the certificate of CCEP.
Features:
• Permeance Measurement Technology
not be interfered by chromaticity, suspended solids and bubbles
• High reliability
strong ability to resist chromaticity, calcium and magnesium ions
• High detection precision, low LLOQ (0.01mg/L), small drift for long-term operation
• Intelligent self-test and self-diagnosis function
• Modular design, highly integrated valve terminal
each valve can be maintained, disassembled and cleaned individually
• 24hrs real-time inspection
• Equipped with alarm function, quality control function and reverse control function
