Calibrating digital hygrometer
I know there are a million threads about humidity and calibrating hygrometers but I have to ask anyways. I have a Xikar digital hygro that I calibrated using the salt in a cap method. Anywhere I put the hygro with a humidity device...a water pillow, cigar.com humi-can, or Xikar 100ct humidification puck, it reads 90%. I'm using Xikar's glycol solution and I'm not cutting it with distilled water. So if I have the Xikar puck in a zip lock back with the hygrometer, would I have to leave it there for hours like with the salt cap? Or can I assume in a small ziplock back the puck is creating a 70% RH enviroment quickly? What do you guys think? I'll probably just take it to the shop tomorrow and calibrate it in their walk in humidor.
