I'm sure there'll be a wealth of knowledge about this. I need a meter to test a couple of wall areas in a house I'm looking at. It'll need to be a sensor rather than pin type as I don't want to leave any marks. Prices range from a suspiciously cheap tenner on ebay and maybe £20-25 at known retailers up to hundreds. What do I need to know and will an inexpensive one suffice? If I find any serious concerns I'll walk or consult a surveyor.
