Product review (5 stars): Great thermometer
I bought this to keep a watch on the temp and humidity in my crawl space.  I've been having some sweating issues around the HVAC duct work and my air handler.  I sealed my crawl space and installed a dehumidifier.  My humidity has dropped from 80% (when I first got the humidity reading) to 39%.  No sweating on my air handler or duct work.  It all looks nice and dry in my crawl space for a change.  I have another AcuRite Thermometer and have been using it for several years.  They're good products and I would recommend them to anybody.
