The Precision Four-in-One combines four American-made instruments in a handsome mahogany wall plaque. Each is in a flanged, solid brass housing. The barometer has a visible mechanism and manually adjustable pointer. The clock is a battery-powered quartz movement with a sweep second hand. The third case contains both a thermometer and a hygrometer which indicates humidity, and a comfort zone where they cross.
