1. Color: Gold 2. Size: 128 mm 3. Tips for checking the device: - Observe the temperature change: Place it in an environment with a large temperature difference from the ambient temperature for some time. When you look at the thermometer, the pointer will change significantly. For example, when placed in the refrigerator, since the mechanical movement changes slowly, the change will occur gradually over a long period. - Observe the humidity change: You can take a deep breath into the small hole at the bottom of the back of the product. You will clearly see the humidity indicator move upwards, and it will drop again after a while. - Check the air pressure change: Since the air pressure varies in different places, the position of the pointer also differs. In some areas, you may also encounter the situation where the pointer changes with the air pressure - extremely low air pressure is below the range, and above the range. The air pressure changes more slowly. Usually, the change is obvious when the weather changes from sunny to rainy or from rainy to sunny. Therefore, if you don't see the moving air pressure arrow, turn the comparison arrow to the same position as the air pressure arrow and then wait patiently for a few days. 4. The black pointer on the large dial is the air pressure arrow, and the silver one is the comparison arrow. The function of the comparison pointer can be adjusted to the same value. Then you can compare and observe whether the air pressure increases or decreases over time. 5. This product is used to measure parameters such as ambient temperature, humidity, and air pressure, and accurately predict future weather changes based on the changes in temperature, humidity, and ambient air pressure. 6. The barometer frame is made of solid wood, and the body is also made of aluminum - magnesium alloy. The surface treatment is fine and it is durable. This is a fully - functional household weather instrument. 7. The barometer serves both as a display and a barometer. It is both beautiful and practical. Owning it is equivalent to having an outdoor barometer, a hygrometer, and a weather station. 8. It is very easy to install. There is no need for a plug or battery. It can be hung on the wall or placed on the counter, which is very suitable for indoor/outdoor wall decoration. 9. The barometer is suitable for all indoor and outdoor occasions and can work normally even at an altitude of 3000 feet. Therefore, you can use it in many geographical areas. 10. It is a high - quality product.
