Temperature and humidity are important factors for your general comfort. This amazingly small mini hygro-thermometer is essential anywhere temperature and humidity are important to monitor. Use it as an indicator of whether your dehumidifier or humidifier aren't working adequately, or whether you need to repair or add such equipment; or to gauge whether the air is getting too dry for your wood floors; and to solve many other mysteries. Its easy to read LCD constantly displays the precise temperature and humidity. With the push of a button, the Max/Min display will indicate the highest and lowest recorded levels of both.
