  • 450 um diameter
  • Extremely low electrolyte leakage properties
  • Stable and reproducible potential
  • Low resistance
Description 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. Low leakage is achieved by using KONBO™, a product combining modern ceramic and conductive polymer technology, as the liquid junction. Electrode resistance is low, an important consideration when making low-noise measurements.

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.

Micro reference electrode
Only 450 µm in diameter and 1 inch long, WPI's new DRIREF-450 reference electrode can be used along with other sensors in space-restricted areas and very small sample volumes.
