I got the Hanna Storage Solution. The Hanna meter says to use it. The yellow TFT meter makes no mention of using a storage solution. I have only had my meters for a few weeks and dont know the long term effect of not using the storage solution. In time i may find out.
The TFT meter is inexpensive and replacing it costs lesss then a bottle of Storage Solution. Replacing the meter every year would not be a big deal.
It looks to me like if you use the meter every few days the probe stays moist. I think the storage solution may be needed if the meter is not used for a while. I don’t know yet is a while is weeks or months.
So we can all experiment together and share our results.
