Product Review

pH probes and ORP probes are sensitive and expensive. Make sure you have the H2O Sync pH Electrode Storage Solution ready to safely store your pH probe in when not being used to extend its life!
Compatible with almost all pH probes, this 3M KCL solution is what most manufacturers recommend for storage. (Some international pH probe manufacturers may also specify 3N KCL or 3NKCL or call it an electrode reference preservation solution which is the same as this solution).
The handy flip top cap snap cap makes it easy to pour even in small storage containers with fewer spills and also avoids larger spills from accidentally knocking the bottle over.
