American NovaLynx Dial Barometer
The 230-P111 dial barometer is rated at a mid-range accuracy of ±0.1 cm (approximately ±1.5 millibars). The 6-inch painted brass housing contains a precision rack-and-pinion temperature-compensated movement, and the knife-edge of the main pointer minimizes parallax error when reading. It is not recommended for use at altitudes above 1067 meters.
