The dual-stream and continuous monitoring capabilities of the Sievers M5310 C On-Line enable efficient, real-time monitoring of two independent sample sources. The analyzer provides automated calculations of percent TOC removal for influent and effluent streams. Make real-time decisions with the Sievers M5310 C On-Line TOC Analyzer. 

Features and Benefits

M5310 C On-Line Features and Benefits

  • Provides readings in only two minutes
  • Automated calibration, verification, and data analysis enable unattended operation
  • Automatically calculates percent TOC removal for influent and effluent streams or samples
  • The Autoreagent feature automatically establishes optimal flow rates for each sample
  • The grab-mode, alphanumeric labeling feature allows individual labeling of each grab sample for easy recall later on
  • Two-stream sample line configuration enables efficient sampling of two independent sample sources, without the need to alter the initial inlet setup
  • Pre-calibrated for simple installation 
  • Minimal maintenance — typically just a few hours per year 
  • Self-contained with small footprint and internal reagent packs — no external chemicals, catalysts, or gas supplies required 
  • Easy data communications — export or collect data via USB, 4-20 mA, or Modbus TCP/IP outputs
  • Integrated On-Line Sampler (IOS) system allows testing of external samples and standards without removing the analyzer from the continuous water source
