Recommendation for surfaces: 827 pH lab

pH Meter: 

• 827 pH lab
  • with EU plug 230 V
  • with US plug 115 V
  • with AUS plug
  • with UK plug)

Electrode:

• Combined flat membrane pH glass electrode

Accessories:

• Cable, 1m (other lengths available)
• Buffer solutions
  • pH 4, pH 7 and pH 9 (30x30 mL sachets)
• Electrolyte solution c (KCl) = 3 mol/L, 250mL (for Ag/AgCI reference system)
• Storage solution for pH glass electrodes

Your advantages:

• The Metrosensor LL combined flat membrane pH electrode has a robust PP body

Practical hints

• pH measurement on a dry surface is not possible. Always wet the surface with one drop of water and then measure. That's all!
