Ambient Weather WS-YG357 Cherry Finish Compact Traditional Temperature + Humidity Comfortmeter Save yourself time and money by monitoring your home with the ComfortMeter. If you have wood cabinets, wood furniture, wood trim, or wood flooring, lack of humidity can actually damage these wood fixtures due to excessive drying out and shrinkage. Conversely, homes with too much humidity are more susceptible to problems such as mold spores and dust mites. The ComfortMeter allows you to keep your home at the optimum levels. When conditions are monitored and kept within the COMFORT zone, you can more easily prevent possible problems. The Comfortmeter thermometer displays temperature in both Fahrenheit and Celsius on the left scale, and the hygrometer shows % of relative humidity on the right.
