Housed in one traditional forged brass case, this combination clock/barometer swivels 360 horizontally and vertically in a brass, perfectly balanced and integrated gimbal so that on one side is the clock and on the other side is the barometer. The gimbal also allows for comfortable viewing from any angle. The clock operates on one N battery. The aneroid barometer is calibrated for altitudes to 3,500' above sea level. Because of the unique arrangement of a clock on one side of the housing and a barometer on the other, this instrument makes an excellent presentation no matter which side of the desk you happen to be sitting on. Overall dims: 5-1/2" (h) x 5" (w). Base Diameter: 3-1/4". Dial: 2-3/8". Base 5.5"(h) x 3"(d). Wt. 2 lbs. 6 oz.
This unit houses a special patented double capsule movement that is factory certified to be accurate to within 0 .2% of real pressure. More noteworthy is that the scale range has changed from the traditional scale of 27.5" to 31.5" Hg to an expanded scale of 28.5" to 30.5" Hg. This exaggerates the needle movement, making a small change in pressure much more noticeable. The barometer movement is calibrated for altitudes to 1500' above sea level. Wt. 3lbs. 3 oz.
