Perfect
This stuff is good. The One Pen from Blue Labs cost too much not to buy the best products to keep it working properly. This storage solution works. I will be buying more to keep my meter safe.

I have used the Bluelab pen a number of times and this is what is recommended cleaning the PH probe and calibrating the PH pen.

Useful!
If you have the BlueLab pH pen you need this. Used to store the pH pen, this solution keeps the pen tip hydrated and in calibration. Without storing properly the tip dries out and then your readings can vary or you may need to re-hydrate and recalibrate more often. I love the pen, and it’s too bad it needs the storage solution, but it sure helps with getting good consistent readings and results !!

Defectuosos por segunda vez al mes de comprarlo
El primero que pedí directamente no funcionaba. Me lo descambiaron y al mes ya no funciona bien. No lo compréis, 75€ tirados a la basura
