The rich, lacquer finished wood framed cherry weather station measures temperature (in °F and °C), barometric pressure (mbar and inHg) and humidity (%).The bezels display an air of quality and accuracy one would expect with a fine, handcrafted weather instrument from Ambient Weather.Reading the barometerIt is highly advisable to lightly tap the glass near the center brass knob with your fingers before taking a barometer reading. The light tap will overcome any friction that may affect accurate hand readings, especially during periods of slow atmospheric changes. The Coast Guard has informed us that tapping the barometer is even required on the most expensive aneroid barometers, because the mechanism is made deliberately “stiff”. The ability if the barometer to indicate changes in barometric pressure makes it a useful instrument in weather forecasting.Weather ForecastingThe weather forecast or pressure tendency is based on the rate of change of barometric pressure. In general, when the pressure increases, the weather improves (sunny to partly cloudy) and when the pressure decreases, the weather degrades (cloudy to rain). The weather forecast is an estimation or generalization of weather changes in the next 24 to 48 hours, and varies from location to location. The tendency is simply a tool for projecting weather conditions and is never to be relied upon as an accurate method to predict the weather. The barometer includes a manually set needle, which is used to mark the current measurement so a change can be seen. Barometric readings should be taken daily. Remember that the rate of change of barometric pressure is important in determining weather changes. You may want to take multiple readings each day during periods of unstable weather conditions.Features:12 inches Long Dials: 2.5 inches Diameter Hang horizontal or vertical Weather station thermometer, barometer, hygrometer Wood base with lacquer cherry finish Faux Glass bezels Fahrenheit temperature scale Barometer CalibrationYour barometer will operate from -100 to 3,000 feet with reliable accuracy. Aneroid barometers have a small screw on the back for sea-level calibration.With a flat blade screwdriver, turn this screw in either direction slightly while looking at the indicator needle. It should move in one direction or the other.Tap the barometer to see where the needle settles. Continue this procedure until the proper pressure reading is obtained.Do not turn the screw counter-clockwise (to the left) too far, since the screw can fall out. After the initial calibration, no further adjustment will be required unless the barometer is moved to a new geographic location.Special Notes and CaveatsThe barometer only works to 3,000 feet. Do not order this product if you live above 3,000 feet. The weather station is intended for indoor use only. The weather station can be mounted horizontally and vertically (by adjusting the dials). The ThermometerThe dial thermometer uses a bimetallic strip wrapped into a coil. One end of the coil is fixed to the housing of the device and the other drives an indicating needle.The principle behind a bimetallic strip thermometer relies on the fact that different metals expand at different rates as they warm up. By bonding two different metals together, the coil bends, causing the needle to move.Bimetallic thermometers are not as accurate as bulb (mercury or red spirit) thermometers. The dial thermometer should require no calibration.The HygrometerThe hygrometer measures the indoor relative humidity. The sensor measures the air moisture by a sensitive mechanical coil spring that is bonded with a moisture absorbent material.Hygrometers register the percentage of water vapor present in the air, compared to the maximum amount that can be present at a given temperature.The coils in hygrometers respond slowly and while humidity levels change abruptly, it can take an hour or more for the meter to reach an accurate reading. Remember that the hygrometer is reading indoor humidity, and is vastly different than outdoor humidity, as reported by the National Weather Service.The BarometerAn aneroid barometer uses a small, flexible metal box called an aneroid cell.This aneroid capsule (cell) is made from an alloy of beryllium and copper. The evacuated capsule (or usually more capsules) is prevented from collapsing by a strong spring.Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer.Many models include a manually set needle which is used to mark the current measurement so a change can be seen.It was invented by Blaise Pascal.
