Barometer Weather Station with Barometer and Hygrometer Thermometer 3 in 1 Wall-Mounted Analog Weather Station for Indoor and Outdoor

describe Color: Gold Size: 132mm Testing equipment advice: 1 . Observe the temperature change: put it in an environment with a large temperature difference from the room temperature for a while and observe that the thermometer will have obvious pointer changes. For example: in the refrigerator because the mechanical movement changes slowly it will take longer to change slowly. 2. Observe the humidity change: you can take a deep breath at the small hole at the bottom of the back of the product and you can clearly see that the humidity indicator is changing upwards. high and the indicator will fall back after a period of time. 3. Observe the change of atmospheric pressure: Due to the different atmospheric pressure in different places the display position of the pointer is also different and some areas may also encounter the situation where the pointer with extremely low atmospheric pressure is in below the range and beyond the range. Atmospheric pressure changes more slowly. Generally speaking this change is evident when the weather changes from sunny to rainy or from rainy to sunny. So if you don t see the barometric needle move turn the comparison needle to the same position as the barometric needle and wait a few days. The black pointer on the big dial is air pressure pointer and silver pointer is contrast pointer. The Contrast Pointer function can be adjusted to the same value. Then you can compare and observe whether the atmospheric pressure has increased or decreased over a period of time. [Three-in-one weather station] This product is used to measure parameters such as ambient temperature air temperature #39;humidity and atmospheric pressure and accurately predict future weather changes based on changes in ambient temperature humidity and atmospheric pressure. 【High quality material】The frame of the barometer is made of solid wood and the case is also made of aluminum-magnesium alloy. It has a good finish and is durable. This is a complete household weather meter. 【Exquisite decoration】The barometer is both a display and a barometer beautiful and practical.
