Dial Barometer with Thermometer Hygrometer Weather Station Barometric Pressure (Metric) Silver 132MM

Dial Barometer with Thermometer and Hygrometer Weather Station - Easy-to-Read Barometric Pressure Measurement - 132mm DiameterThis portable weather station consists of a barometer, thermometer, and hygrometer.Measures barometric pressure (hPa), temperature (°C), and humidity (% RH).Metric system.Its advantages are simplicity, reliability and ease of readingLong-term use without special maintenanceThis dial weather station is made with high-quality materials< /p>NotesPlease hang the weather station in a well-ventilated area, away from sunlight and corrosive air.Use within the required range and do not expose it to water or steam.Avoid strong vibrations and shocks, and do not disassemble it yourself.Barometer SettingObtain the standard atmospheric pressure from your local observatory or other source.Note: Use within the required range; do not allow it to come into contact with water or steam.This thermometer and hygrometer are already accurate.The user does not need to readjust.Use the adjustment tool to adjust the screw on the back of the barometer so that it points to the air pressure reading you are getting.The needle face can be adjusted manually, and the changed air pressure value after adjustment can be compared. Press gently on the face to eliminate friction caused by the transmission movement. To avoid damage to components, adjust the pointer slowly.If the adjustment range is wide, please adjust it several times separately.The product is used to measure changes in parameters such as temperature, humidity, and atmospheric pressure in the environment, and to accurately predict future weather changes based on the trend in ambient temperature, humidity, and atmospheric pressure.This is a complete home weather forecasting instrument (barometer) Product FeaturesProduct Name: Thermometer, Hygrometer, Barometer Three-in-One Weather StationModel Number: THB9392Measuring Range: 960~1060 hPa, -30~50℃, 0~Rh;Resolution: 1 hPa, 1℃, 0.2% RhMeasurement Accuracy: +/-5 hPa, +/-2℃, +/-5% Rh (40~70% Rh)Mechanical movement, no battery required, easy to use  Tips for testing thermometers:1. Observe the temperature change: place it in an environment with a large temperature difference compared to the ambient temperature for a certain period of time, and there will be obvious changes in the thermometer needle.For example: put it in the refrigerator; because the mechanical movement changes slowly, it takes longer for the temperature to change gradually.2.Watch the humidity change: You can take a deep breath at the place with a hole at the bottom of the back of the product, and you will clearly see the upward change of the humidity pointer, and the pointer will fall again after a while.

Thermometers that meet the above two points are normal products. Please use it with confidence! thank you

3. Watch the air pressure changes: Due to the different air pressures in different places, the display positions of the pointer are different, and some areas may also encounter the situation where the pointer with very low air pressure is deviated to the lower range and exceeds the range. . Atmospheric pressure changes more slowly. Generally, the change will be evident when the weather changes from sunny to rainy or from rainy to sunny.Therefore, if you do not see the air pressure needle move, please turn the comparator pointer to the same position as the air pressure pointer, and then be patient.Wait a few days.Silver aluminum alloy outer ring, PMMA plastic lens, silver setting knob, imported movement, multifunction display, large dual-scale display panel with time change, temperature and humidity meter with logo.The dial is made of imported embossed aluminum-magnesium alloy with refined craftsmanship, showcasing a pattern throughout.Features:1.Movement-----Uses standard EU movement2.The dial is made of one-piece stamped aluminum-magnesium alloy4.
