product descriptioncommodity name:Barometerproduct material:Metalcommodity color:silver whiteMax Measuring Temperature: 49°C & UnderMeasuring range: -30 ~ 50C, 0 ~ 100% RH, 970 ~ 1050hPa,Resolution: 1C, 2% RH, 1hPaMeasurement accuracy: ± 2C, ± 5% RH (40 ~ 70% RH), ± 5hPa (970 ~ 1040hPa)Diameter: 128mmThickness: 41mmWeight Weight: 130gPackage List:3 in 1 BarometerX1Barometer readings,1. To determine the direction and trend of atmospheric pressure changes, first tap the glass surface of the barometer with your finger, and then turn the adjustment knob on the lens to align the pointer on the lens with the barometer pointer. After a few hours, tap the surface of the barometer. Observe the change direction of the barometer pointer2. If the pointer moves to the right (clockwise), it means that the air pressure has increased, which is what we call "the pressure rises."3. If the pointer moves to the left (counterclockwise), it means that the air pressure has decreased, which is what we call "the pressure drop."4. The direction in which the pointer moves represents the changing trend of the weather. Moving the pointer to the right means that the weather will turn right. A pointer moving left will indicate that the weather will turn bad.5. After determining the barometric pressure change with two readings, adjust the alignment of the contrast needle and the barometric pressure hand again for the next reading as described above. A small change in barometric pressure pointer is not important, but the readings continue in the same direction for a short time Minor changes will be more important.
