I dont have a picture right now, but my test chamber is easy to describe.
I have an airtight, plastic humidor jar. I have this jar loaded with about 20 cigars, plus a 65% Boveda. I know with 100% certainty that the inside of the jar is at 65%. I only open the jar about once a month, so I also know that the cigars are exactly at 65%.
When I want to test one of my many hygrometers, I just put it inside the humidor jar, and let it sit for 48 hours. Thats it, no Humidipak bag, no salt test. It is without doubt, 100% accurate.
