Digital Hygrometer: Adjustable or with memory option?

[buzz]

Thanks basil,

Please correct me if I am wrong guys but it seems that the more important thing would be the consistency of the humidity and temperature levels, not the actual values. So if my hygrometer is 3% RH off and 2 degrees off, I shouldn't worry as long as it is consistent all day long - right? So with that in mind maybe having the memory option would be more beneficial to insure (or ensure?) that my minimum and maximum values don't swing too much?

Edit: I said the values don't matter as much as the consistency - I should have added that as long as the values fall within the appropriate ranges for a humidor.
