I’ll be shipping an apex temp and ph probe to someone and just wondering how am I supposed to keep the probes wet? I would just put them in a plastic bag but it could leak.
Read how to take care of your pH electrodes including calibration, conditioning, handling, how to refill, and storage and protection to prevent breaking.
A little balloon with a zip tie. Put a little tap water in the balloon. I think it just needs to be moist not wet. Even if it dries out for a brief time, should be alright on a ph probe.
