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.
Super Dry
SUPER-Dri-Ref, a reference electrode with a diameter of 2mm, does not leak electrolyte at all. Exhibiting the electrical stability of a classic flowing junction reference cell, this electrode exhibits low resistance and a stable half-cell potential essentially independent of sample electrolyte concentration. SUPER-Dri-Ref is ideal for small volume and low salt concentration measurements.
