Total Phosphorous/Nitrogen (TP/TN) Automatic AnalyzerNEW

TPN-100

TPN-100

Toray’s total phosphorous/nitrogen automatic analyzers rapidly and accurately perform automatic analysis of total phosphorus and nitrogen content in rivers, lakes and marshes, sea areas and plant discharge online.
They use a measurement method (autoclave method) conformant with official methods, producing the same values as hand analysis, enabling them to perform highly reliable measurements.
These innovative devices, designed for convenience and economy, are easy to operate, easy to maintain, and highly reliable.

Features

  • Official method conformant measurement method
    These meters use an official method-conformant measurement method (autoclave method), producing results which correlate closely to manual analysis results.Compared to the ultraviolet degradation method, they produce highly reliable measurement values.
  • Greatly reduced test reagent usage (1/2 of past Toray models)
    These devices use half the test reagent volume as past Toray models, and are made with components that offer long-term reliability, reducing maintenance costs.
  • Negative suction method for exceptional SS performance
    Negative suction design prevents dirtying of sampling tube.Resists clogging and ensures long-term, stable measurement.
  • Space-saving
    No maintenance space is needed for the rear or left side of the device.Takes little space, making it possible to use space effectively.
  • Other
    Load calculation function, built-in printer, USB memory stick function.Can be installed together with UV and TOC meters (including load calculation for three constituent measurement)
