The German-designed Mini Hygro-thermometer is essential anywhere temperature and humidity are important to monitor. An easily readable LCD constantly displays the precise temperature and humidity. A Max/Min function indicates the highest and lowest recorded levels of both. Put one in each room. The Hygro-thermometer is also ideal for wine cellars, cars, greenhouses and humidors. Use in tandem with your Ultra-Aire, Santa Fe or SaniDry dehumidifiers.
