Hi all. I just posted to a thread that was looking for info on how to calibrate a hygrometer. (https://www.backyardchickens.com/forum/viewtopic.php?id=615625) Rather than hijack that thread, I thought I'd post new. Alienchick posted a really useful method for calibration, using salt and water. This tests the accuracy of the hygrometer at 75% RH, at room temperature. Is hygrometer calibration something that comes up regularly, and is it important to you? Would it be useful to have additional ways to calibrate for other humidity levels?

Here's how I see it. http://cmfarm.us/HygrometerCalibration.html
