Color: GoldSize: 132mmAdvice on test equipment:1. Observe the temperature change: Place the device in an environment with a significant temperature difference from room temperature for a period of time and observe the thermometer's pointer movement. For example, placing it in a refrigerator will show a gradual change due to the mechanical movement responding slowly.2. Observe the humidity change: Breathe into the small hole located at the bottom of the back of the product. You will see the humidity indicator rise and then gradually return to its original position after some time.3. Observe the atmospheric pressure change: Atmospheric pressure varies by location, which affects the position of the pointer. In areas with extremely low atmospheric pressure, the pointer may fall below or beyond the scale. Changes in atmospheric pressure are typically slow and become noticeable during weather transitions, such as from sunny to rainy conditions or vice versa. If no movement is observed, align the comparison needle with the barometric needle and monitor over several days.The black pointer on the large dial indicates atmospheric pressure, while the silver pointer serves as a reference or comparison needle. The comparison needle can be manually adjusted to match the current reading, allowing users to track changes in atmospheric pressure over time.Three-in-one weather station: This device measures ambient temperature, air humidity, and atmospheric pressure to help monitor environmental conditions.High-quality material: The frame is constructed from solid wood and the casing is made of aluminum-magnesium alloy, providing a smooth finish and long-lasting durability. This is a complete household weather instrument.Exquisite decoration: The device functions as both a decorative piece and a functional instrument, combining beauty and practicality. It serves as a temperature, humidity, and pressure monitoring tool suitable for home use.Easy to Use: No batteries or electrical connections required. Can be wall-mounted or placed on a flat surface, making it ideal for indoor or outdoor display.Indoor and Outdoor Use: Suitable for use in various environments, performing reliably even at elevations up to 3000 feet. Ideal for a wide range of geographic locations.
