This storage solution is for conditioning and extending the service life of regular pH and ORP electrodes/testers/sensors. pH/ORP electrodes that are stored dry will lose their sensitivity and accuracy temporarily. They can be restored by soaking in the KCL solution. Keeping pH/ORP electrodes stored in the storage solution when not in use is a recommended practice. The storage solution works well for Apera Instruments regular pH and ORP meters and electrodes e.g. PH20, PH60, 201T-F, 301PT-C.
