Milwaukee PH calabration fluid?

[Red-Cricket]

Hey Folks, Is there any fluid that I can calabrate my milwaukee 2000? (mine all evaporated). Any suggestions on how to make the unit last? Do you put cap back on? Or just prt tester in liquid without cap? Instructions SUCK! Thanks All

I use this stuff

Hydroponics - pH, TDS, PPM, EC Measurement - pH Electrode Storage Solution - 8oz.

Only because someone told me to, I couldn't tell you if it makes a difference or not, I end up replacing my pen about once a year because I lose it or drop it one too many times, for which the solution is no help.

Edit: As for calibration, break your pen more often and you won't run out
