The instruments are mounted in a panel of hand-rubbed oak. The precision instruments (2 3/4") are surrounded by solid brass bezels and have a one-year manufacturer's warranty. The dual scale thermometer reads in both Fahrenheit and Celsius, and the hygrometer measures the percent of relative humidity. The barometer reads both inches and milliners of mercury, and has a moveable hand to record a previous reading. This is particularly useful for predicting weather changes approximately 12 to 36 hours in advance. The panel measures about 10 1/2" by 13" and has a keyhole slot for quick and positive wall mounting. Shipping weight is calculated at 4 lbs.
