The brass Endurance 085 Comfortmeter is compact in size for areas where wall space is limited. This instrument is designed to indicate optimum climate conditions when both hands cross in a limited area of the dial called the COMFORT Zone. The thermometer on the left side of the dial displays the temperature in both Fahrenheit and Celsius. The hygrometer shows percentage of relative humidity on the right. Constructed with a high luster maintenance-free brass finish, this comfortmeter is part of the extensive Endurance Collection. The patented Slide-n-Lock Mounting System eliminates the need for visible mounting screws and allows for easy removal for necessary adjustments. The Endurance 085 Comfortmeter is splash resistant and has a lifetime warranty on finish and movement.
