pH Combination Electrode, DG115-SC, Glass Body, Mettler Toledo, 89806

Mettler Toledo™ pH Combination Electrode, DG115-SC, Glass Body, 89806

Features:

• Combined glass pH electrode with fixed ground-glass sleeve junction for direct pH measurement and acid/base titrations in aqueous medium — integrated glass sleeve allows secure fit in titration head
• Sleeve junction provides stable measurement signal that is minimally influenced by stream potentials
• Junction’s large surface prevents it from becoming blocked, and removing precipitates such as silver chloride is easy
• 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
• Silver ion trap to ensure that the electrolyte is absolutely free from silver ions — prevents contamination of sleeve junction by silver sulfide
• S7 screw cap
• Detachable cable
• Individual quality certificate
• Unique serial number

Applications:

• 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).
