Galvanised Barometer

Pressure, pressure, pressure: it's what this beauty handles best! Intended for indoor or outdoor use, this barometer is both stylish and functional. Dimensions: 12cm Diameter This Barometer has been regulated to function at an altitide of 67m (210ft) above sea level. If the altitude of our locality is different (you can check with your local Met Office), you will need to re-set it. 1. Compare the reading with another barometer you know to be accurate, or with your local weather network. 2. If the reading is lower than your local standard - turn the adjusting screw on the back to the left with a flat blade screwdriver to obtain a positive compensation. If the reading is higher, turn to the right. 3. After adjusting, tap glass gently so that the deviation still remainging can be corrected by means of the adjusting screw.
