• Use a soft microfiber cloth to gently remove dust and dirt without damaging the protective layer.
• Place the weather station in a dry place to prevent moisture and corrosion damage, especially in damp environments such as boats or campers.
• Avoid strong cleaning or polishing agents that may damage the protective coating of the barometer housing.
• Re-calibrate the weather station at the start of the season, after long storage or if you have any doubts about its accuracy.

• Why is a weather station important on board?
A good weather station is essential for monitoring the indoor climate for comfort and protection of sensitive equipment and textiles on board.

• How do you read a barometer?
A barometer displays the current air pressure. For a weather forecast, you look at the difference from the previous reading and how quickly the pressure has changed. Rapid pressure changes indicate short-term weather changes; slow changes indicate longer-lasting weather changes.

• How does a hair hygrometer work?
A synthetic hair hygrometer measures relative humidity using a hair that expands at high humidity and contracts at low humidity. This movement is transferred to a dial that displays the humidity percentage on a scale.

• How does the thermometer on board or in the house work?
The indoor thermometer is specially designed for maritime conditions on boats, ships, and yachts and accurately measures the temperature inside, on board, or indoors. It remains reliable in changing weather conditions at sea.

• Where do I hang my weather station?
Avoid locations in direct sunlight or above a heat source such as a stove. A prominent spot on the boat or in the house ensures that you immediately notice changes in pressure, humidity, or temperature.

• How do I adjust my weather station?
Most weather stations are factory-set. You can look up the current air pressure online and adjust the needle if necessary with a screw on the back of the mechanical barometer. If you have any questions, we're happy to help!

• Does a weather station work at any altitude?
Barometers are set to sea level. Calibration is required for use at higher altitudes, such as in mountains.

• Does the weather station come with a warranty? Yes, when you purchase a Wempe barometer, you receive a three-year international warranty. This warranty covers damage or defects not caused by external influences or improper use, including issues with functionality and the clock.
