This product is made on the physical principles of the weight of the atmosphere acting on all parts of the earth,and the higher the site,the shorter the column of air and hence its weight and pressure,weather change due to air pressure variation transferable via high precision mechanical gearing to the pointer displaying on the dial of altimeter/barometer,it serves to measure accurately for site altitudes,height differences,atmospheric pressure and for weather forcasting Barometer measuring range:580-1040hpa; Altimeter measuring range:0-5000m Thermometer measuring range:-30-50 celsius degree Resolution:100ft increment Dimensions;3.34×2.6×1.09 inchs Dial size:2.36 inchs Refer the actual site altitude to maps,footpath signs or source available,Air pressure variations/weather changes may constantly affect the altitude reading hence the necessity to compare the known reading of the heights occasionally while climbing or walking.
