Electrolyte-100sat is a saturated KCl solution (4.76 M @ 25 °C). This electrolyte is ideal for reference electrodes, that are used for handheld measurements and/or (long-term) standalone monitoring. All reference electrodes of SWAP instruments are filled with this gel (e.g., REF-12-0-A, ORP-30-1-BNC, ORP-30-1-A, ORP-40-4-A, ORP-80-4-A, ORP-30-1-D, ORP-40-4-D and ORP-80-4-D). This gel is harmless for the environment.

Reference electrodes do need maintenance. This includes, refilling of the chamber(s) of the reference electrode with saturated KCl (4.76 M @ 25°C). Maintenance ensures good measurement results!

For more information about refilling the reference electrodes of SWAP instruments, please watch our instructional video.
