I just got this meter, It is a Hanna HI981239 Combo Meter and in the instructions it says to put a couple drops of storage solution in the cap before storing it. I don't have any storage solution, I intend to get some but that won't be for a few days, if I store it without the storage solution is it gonna fuk up my meter......is there anything else I can use in place of storage solution? THANKS in advance
