Portable tester
When i was under one of my houses in the crawl I became a little nauseous. Is there some kind of tester I can carry around with me while I am under there? Will it work if I just take along a carbon monoxide sensor that would normally be affixed to a wall? Of course it could have been some other gas too. Is there some multi-meter I can use to take along?
