Damp

Thank You Nigel

Certainly given me something to think about 

No problem, it seems the inductive pinless technology is drifting down to cheaper price points now. A search on eBay for ‘pinless moisture meter’ is bringing up some products between £20 and £50 which was never the case a few years ago.

Cant vouch for there ability but at least they are becoming cheaper. Great for regular checking as IMO, an annual damp test is often too late. Best to catch ingress early as possible.

I worked at a caravan dealers for three years after retirement handling part exchanges and the only meter we would use is the Protimeter. The great benefit is that the display is visual. On many occasions I have checked a part exchange which on the face of it is completely dry and found damp in the usual suspect areas, around the toilet, corners of the awning rail and window apertures. What I particularly liked was the colour coding : green for fine, yellow for a little suspect and red for immediate action. However the readings do need interpretation. If when when checking around a front window the whole area is green, except for a small area of yellow, new window rubbers and resealing should sort that out. However if the whole of one side is reading yellow then that requires looking at quickly since in six months time it could be red. I have purchased my own Protimeter for peace of mind and every three months do a quick damp check. If putting a caravan into storage for the Winter I would certainly have it checked and again in the Spring.
