  • 4.7 mm diameter
  • Extremely low electrolyte leakage properties
  • Stable and reproducible potential
  • Low resistance

Low leakage properties

Dri-Ref™ reference electrodes were developed by WPI to have extremely low electrolyte leakage properties, hence the name "Dri-Ref". In addition to this key feature, these electrodes exhibit stable and reproducible potential and low resistance. Stored in KCl when not in use, they have a long life expectancy.

Use with ion selective electrodes

Although the internal filling solution contains KCl, the low fluid leakage means Dri-Ref may be used in combination with ion selective electrodes, including those for K+ and Cl-, without significant contamination from the reference electrode.

Chemically resistant

The Dri-Ref electrodes are chemically resistant to strong acids and alkalines. Dri-Ref electrodes are not suitable for use in organic solvents.
