DG115-SC - نظرة عامة - METTLER TOLEDO


Combined glass pH electrode

Combined glass pH electrode with a fixed ground-glass sleeve junction for direct pH measurement and acid/base titrations in aqueous medium.
Especially suitable for:
  • Media with low ion concentration (e.g. low ion conductivity water)
  • Polar solvents such as acetic acids or alcohols (e.g. titration with perchloric acid in acetic acid or with sodium methylate in methanol).

The sleeve junction provides a stable measurement signal, which is hardly influenced by any stream potentials that occur in stirred solutions. The large surface of the junction prevents it from being blocked by precipitates which can be easily removed.
Features and Benefits
  • Fixed ground-glass sleeve junction
  • Integrated glass sleeve for secure fixation in the titration head
  • ARGENTHAL™ reference system for increased life span and heat resistance, which requires only an AgCl-free 3 mol/L KCl electrolyte
  • Refillable reference electrolyte (Standard 3 mol/L KCl)
  • 25 mL of reference electrolyte (3 mol/L KCl) included in standard delivery
  • Silver ion trap to ensure that the electrolyte is absolutely free from silver ions. This prevents contamination of the sleeve junction by silver sulfide
  • S7 screw cap
  • Detachable cable
  • Individual quality certificate
  • Unique serial number
