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. Dial: 4". Base: 5-1/2". Depth: 2-7/8". Wt. 3 lbs. 3 oz.
