Recommendation for wine: 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:

• Unitrode – combined LL pH glass electrode with Pt 1000 temperature sensor, fixed ground-joint diaphragm, fixed cable

Accessories:

• 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:

• Wine just loves electrodes. Electrodes love wine, too! So much that they drink some of it and get a little "drunk". A "drunk" electrode is not doing very much good. The Unitrode loves wine, too, but we never managed to get it drunk and we guarantee that you will not manage either. A conventional electrode would be covered by the constituents of wine in a short time and you'd find the nicest wine not only "sticking" onto the diaphragm but also getting into the electrolyte inside the elctrode. Not so with the Unitrode: The special ground joint diaphragm allows an optimal electrolyte flow which prevents any contamination of the reference electrode with wine
• With the Metrosensor Unitrode, even on-line measurements don't increase the affinity of the sensor towards wine!

Practical hints

• Rinse the electrode thoroughly between the measurements with distilled water
• Don't store the electrode in the sample. Use the electrode holder filled with 6.2323.000 Storage Solution
