103 | precision aneroid barometer

general information:

• aneroid barometer for the measurement of the absolute atmospheric air pressure
• for indoor use
• precision movement with five aneroid capsules made of copper beryllium alloy, inherently stable
• nearly free from ageing, hysteresis and elastic effects
• compensation of the influence of temperature on the capsules and the transmission system by means of a bimetal within the whole measuring range and within the temperature range from -30°C to +40°C
• transmission of the motion of the aneroid capsules to the axle of the needle by means of drive and segment with finest gearing
• mineral glass cover
• diameter of housing: 165 mm
• further modells out of the series: thermometer (103T), hair hygrometer (103H), tides clock (103TD) or quatrz clock (103U)
• design types: brass polished, brass chromed

technical data:

• meas. range: 890 hPa to 1,050 hPa
• accuracy: ±0.7 hPa
• scale division: 0.5 hPa
