Hygrometer calibration/ Boveda pack question

SmokinPhysics · 05-23-2012, 08:29 PM

Let me start by stating I have a Xikar round, adjustable calibration hygro.

I ran the salt test on it, letting it set 36 hours, and I never got it to read any more than 62%. So then I went to my B&M to try to get a Boveda calibration pack, and they were sold out. So I instead went ahead and got a 75 pack and have it setting in a quart-size ziploc with the hyg. Now, I will mention that the ambient temperature fluctuates 72-74°, and so that presumably affects rh. I guess my biggest question is how accurate can I expect that 75 pack to be setting in the ziploc?
