Just dropped $400 on a new moisture meter and it's already paid for itself
I was doing a glue-down vinyl job in a basement last month and my old meter gave me a borderline reading. I almost went ahead, but decided to rent a pro-grade one for a day to double-check. It showed the slab was way over spec, saved me from a guaranteed callback. Bought the same model, a Wagner MMC220, for about $400 out of pocket. Already used it on three jobs where the concrete felt dry but wasn't. Anyone have a different brand they swear by for tricky moisture checks?
