Description

Precision aneroid barometer dial readout (two hands). Range 500 to 1100 mbar (hPa). Least count 1 hPa, estimate to 0.1 hPa.

The dial is graduated from 0 to 100 hPa. Short hand: multiply readout by 10 to get the coarse reading (multiples of 100 hPa).

Users are advised to set up the barometer on a horizontal surface and to gently tap the barometer before reading to release any friction in the mechanism.

For more information, see item 0170.
