Hygrometer Problem

[Iluveggers]

Hey all,
I calibrated 3 therm/hygrometer combos yesterday. Unfortunately the hygrometers were showing 71, 70 & 68.
I used non-iodized salt as that was all we had. Should I try it again, or assume they are all around 5% lower? Would iodized salt make a difference?

Thanks!

I'm checking un-replied threads and I saw this. Iodized or not, shouldn't matter. I see that you saw my reply to another thread on the NR360 about air flow to the meter. Any chance that is the issue you are having?

I ran it again the next day and one was showing correct & the others 2% lower! I think maybe I didn’t mix the salt in well enough. Thank you though!
