Bought my first one today. Looks like an oven thermometer. "Lockdown" brand for $9.99. Never used one before in any of my gun safes. At the price, considering buying one for each safe. Curious as to whether others use these things to judge humidity. Seems awfully cheap.

Have one with a barometer and thermometer, and one in the humidor for cegars. Yes, they work, but they are not "real time" instruments- there is a lag of minutes when changing.

In the Batcave I have a number of.... storage containers. And a portable dehumidifier. Set on a timer to run 2 hours a day, sealed room, does a good job. Found the dehumidifier on Craigs list for $30. Tank holds 3 gallons of water.

I use them, they work. Not much you can do though unless the safe is airtight.
So, what's an acceptable humidity level for firearms storage ? I'm pretty good at using Remoil and gun grease on most things but some don't get out much and, of course, don't get inspected very often. Thanks for the reply, btw.

From what I’ve found, as long as firearms are cleaned and put away inside a well insulated indoor environment (not the garage) rust shouldn’t be a problem.

Just my 2€

I keep my house a constant 71 degrees and about 55% humidity year round and will still get some fine powdering of rust that needs wiped down about once a year.

Right now I have three safes and three "gunlockers" scattered about. Rechargeable dessicant goes about a week before it's full in the 50 gun locker. Considering a golden rod or similar but concerned about those perhaps actually causing condensation as that one's in the garage where temps vary widely. Others are on two floors (attic and closets). From what I understand the golden rod types simply provide a bit of heat and don't draw moisture out (I may be totally wrong). Gonna put the hygrometer in the big one today to try it out.

I’ve seen 50% stated as acceptable. Is that science or “playing by ear”, is hard to tell. In my safe it can drop below 30 in the winter and go above 70 in the summer. All my modern guns are okay with regular shooting and maintenance.

"Humidity Rod"
Here is the one I have in one of my Safes! But it was around $33.00.
But works great! It plugs into the wall outlet behind the Safe.

In the other Safe I have two Desiccant Canisters that when the Center of the Cap turns Pink. They can be recharged in the Oven for 3 hours at 240 degrees then the Center of the Cap turns Blue. $15.99 each on Amazon.

Well, after a few days the Hygrometer reads "55" so that's not too bad if it's accurate. Overdue checking/oiling stuff anyway. Thanks for the replies.
