I just recieved a Hanna pH/EC/temp meter. In the instructions it says to use a few drops of storage solution (HI 70300) in the cap. That product did not come with the meter.
So I'm curious A: what the solution is, and B: is it necessary, and C: are there any substitutes? It seems it's just a pH neutral solution yet it states not to use distilled or de-ionized water.
It also says to clean it monthly with cleaning solution (HI 7061) which also didn't come with the meter so I'm curious if there are substitutes for this which is described on their website as a general purpose cleaner for electrodes.
