Product review (5 stars): Easy To Use
This is an easy to use humidity and temperature reader. It comes with easy to understand instructions, a nice case and a battery.

I have three floors on my house. I also have a furnace and central air conditioning unit that includes a humidifier that I use during the winter.  Because my house is old and the air ducts in it were created when central air conditioning was in its infancy temperature and humidity levels vary from room to room.  I plan to make some improvements to my house and this device will give me an idea of what can be improved when it comes to my air conditioning and heating.

This is easy to use. When it is turned on the first numbers that appear are the relative humidity and the temperature. This changed room to room for me with a bigger difference going from my basement to the top floor of my house.

There is a min/max button which shows the minimum and maximum humidity level recorded.  There is a hold button so the display won't change if you need to record the information. There is also a button that shows the dew point and wet bulb but I have not used either of them.

This is easy to use. This comes with a nice case. It also comes with a battery. It works well.
