Customer Reviews
Now I can tell what the temp and humidity is in both levels of my house. Posted 09 January 2007
I always wanted to see what effect the washer and dryer had on the humidity levels in our home, so I bought two of these and keep one in the basement (where the laundry is) and one upstairs. We can monitor the effect the clothes washer has on both levels of the house.
These devices help us know, and then, regulate the temp and humidity more accurately and also act as a back-up to our furnace/air conditioner's main thermostat.
