WARNING: LONG BORING QUESTION
ok I just bought a new digital hygro, the user calibrated one. And I thought I might salt test all the others at the same time just to recheck everything. So I performed 2 trials (thus far) the first time I used a rubbermade clear cookie container. placed a about a 1/6th cup of dampened salt and the three hygros (one is a analog that came with my Savoy humi, next is a diamond crown digital, then the user calibrated digital. I left it in there for 2 days and the reading did not make me happy, the analog was 70 the diamond crown was 68 and the user calib was around 71, so I give up on that trial, I calibrate my user calibrated so it is accurate, and then I do it again the second time was in a smaller containerwith all the hygros facing down. the analog was 75 the user calib was 79 and the diamond crown was 66. ok again not happy with the results. so I re calibrate and throw them all into my one humidor all attached to the top. I leave them in there for a few hours and the analog is 69ish the diamond crown is 66 and the user calibrated is 70, then I just checked again a few hours later and the user calibrated is 69 the analog is 68ish and the diamond crown is 67-68(jumped). so I am wondering if there is a proper way to do the salt test so I can tell which ones are accurate. it seems if I just leave them in the humi they all have the same Rh which is of course a good thing but why does it not work during the salt test?
Thanks in advance for any advice
