Maximum Predictor Barometer (Analog)

The Maximum Predictor Barometer is a meteorological-grade barometer at an affordable price for any home weather enthusiast. Measurements are taken over a three-inch scale of mercury (28.5-31.5″), the Predictor is accurate to ±0.16″, far better than any digital home weather station. A resettable pointer lets you track changes in barometric pressure.

The precision German movement of the barometer is housed behind a cutaway dial, which shows the traditional barometer nomenclature, “Rain,” Change,” and “Fair.” For high-altitude installs, the Maximum Predictor barometer can be adjusted to any elevation up to 6500′.
