Remind: many customers do not understand, mistakenly believe that the white pointer is the degree of air pressure，In fact, the white pointer is just a contrast pointer,Because the pressure change is very small, for example, the white pointer is manually adjusted to the same position as the black color, so you can tell whether or not the air pressure is high or low tomorrow.The white pointer is manual. It does not change itself.
Measuring range: pressure 960 ~ 1060hPa (hPa), temperature -30 ~ 50 ℃, humidity 0 ~ 100% Rh; special remind the highland area or mountain friends, be sure to confirm your atmospheric pressure in our barometer range The Atmospheric pressure below 960hpa or higher than 1060hpa will appear to the most left or right can not measure the situation.

Above the pressure data is collected by the dispensers network, the pressure will change with the weather and the season. Only for consideration.
If it is a plateau or high altitude, it will exceed the scope of use and can not be used normally. A similar situation may be encountered, or the pointer may not move in the following direction.
