Stuart Bates Posted September 12, 2010 Share Posted September 12, 2010 A week ago I bought a de-humidifier. Not really sure why because I never thought that humidity was a problem where I live. However, it has been a wet winter and I thought why not? Well having had the de-humidifier on and off for 5 or 6 days now I was astonished at the amount of water that it had extracted in that short time - at least 2-3 litres, I should have measured it, I know. My unit doesn't keep the humidity at a constant level - perhaps I should have bought one that did. Does anyone have recommendations as to what the humidity range should be in a collection room? I have heard 40% but I have no idea what is apposite. Stuart Link to comment Share on other sites More sharing options...
Mervyn Mitton Posted September 12, 2010 Share Posted September 12, 2010 Hi - Stuart. I have used a de-humidifier for years and as you say it is amazing how much water it extracts. Truncheons - being old wood, dry out and crack so the machine does have a use. The flat also used to have a lot of static electricity - could give a nasty shock. For the dry months I had a machine to add humidity. You can buy a humidity gauge and I try to keep at about 60 %. You may find your cloth covered helmets need to be below this - trial and error.

Stuart Bates Posted September 12, 2010 Author Share Posted September 12, 2010 (edited) Thanks Mervyn. I'll see where I can buy a gauge. Stuart Edited September 12, 2010 by Stuart Bates Link to comment Share on other sites More sharing options...
Brian Wolfe Posted September 13, 2010 Share Posted September 13, 2010 I've used a dehumidifier for several years and just keep it as dry as possible with no gauge. IN summer the thing runs 24/7 but the winters here are dryer so it runs once in a while. I do believe a gauge would be a good idea and may look into one as well.

Stuart Bates Posted September 13, 2010 Author Share Posted September 13, 2010 (edited) Brian, I ordered an IC7202 Jumbo Display Digital Hygrometer this morning. It is quite inexpensive and gives temperature as well as humidity. Stuart Edited September 13, 2010 by Stuart Bates Link to comment Share on other sites More sharing options...

Dieter3 Posted January 18, 2011 Share Posted January 18, 2011 I have heard 40% but I have no idea what is apposite. Stuart 40-50% is good for a mixed materials collection. Link to comment Share on other sites More sharing options...
Stuart Bates Posted January 18, 2011 Author Share Posted January 18, 2011 Thanks Dieter. My de-humidifier does not seem capable of getting below the 50% mark. I shall have to investigate further. Stuart Link to comment Share on other sites More sharing options...

Stuart Something else worth looking into, but perhaps hard to control to fine degree, is temperature - and it's relationship to RH. Could be very helpful for you to determine the best way to maintain a collection within your circumstances. Link to comment Share on other sites More sharing options...
Stuart Bates Posted January 18, 2011 Author Share Posted January 18, 2011 Dieter, My gadget shows both temperature and relative humidity. I shall look into it further but am hoping that a member has the answer Stuart Link to comment Share on other sites More sharing options...
