M1-BARO electronic barometer measures barometric pressure. It is designed for outdoor use;
therefore, it comes with a casing of painted light-alloy direct-solar radiation shades for minimizing thermal drift of the electronic components. Upon request it is also available in a rectangular aluminum casing version. Still, its pressure transducer is temperature compensated and functions in a range between 800 and 1100 mill bars. This instrument comes calibrated to mean sea level pressure.
