• Continuous flow design provides rapid TOC response.
  • Gas and reagent-free operation.
  • Ultra-low TOC detection limit and wide dynamic range.
  • Meets USP, and EP 2.2.44 requirements.
  • RS232 and 4-20 mA outputs.


  • Continuous analysis, no time-consuming batch measurement cycle.
  • Obtains real data as it happens and reacts with alarms when necessary.
  • Low maintenance: no gases or reagents to handle, store, or replace.
  • No membranes or moving parts simplify routine maintenance and extend service intervals.
  • Diagnostics keep the operator informed of instrument status.
  • User-defined password protects setup and maintenance menus.
  • Connecting two TOC sensors to one 770MAX reduces the cost per point.
