Great Tool to adjust your Air Conditioner, Humidifier or Dehumidifier

Most experts recommend an indoors air humidity level between 40% and 60% as most comfortable. If the air is too dry it can strain the respiratory tract, while high humidity levels promote the growth of mold and germs in the walls. This meter will allow you to check the humidity level and temperature.
Place the meter in a room and after 5-10 minutes it will give you a stable reading of the current conditions. You then can use the readings to adjust the air conditioner or humidifier to your needs in every room.
