Fischer 103CR-mmHg German Precision Aneroid Barometer
Aneroid barometer for measurement of absolute atmospheric pressure. Precision movement with a self-stable set of five aneroid capsules made of a copper-beryllium alloy.
Measuring Range:
- 667.5 to 787.5 mmHg (890 to 1050 hPa)
- Adjusted for sea level and suitable for use at elevations up to 760 ft (231.65 meters) above sea level.
Accuracy:
- ± 0.5 mmHg (± 0.7 hPa)
- Graduation: 0.38 mmHg (0.5 hPa)
Available Units:
The barometer is available with faceplates in multiple measurement units, including mmHg, hPa, and InchHg, with the mmHg as the unit on face dial.
The aneroid capsules are nearly free of age-hardening, hysteresis, and elastic after-effects. Temperature influence is compensated by a bimetal system, ensuring accuracy over the full measuring range and in temperatures from -30°C to +40°C (-22°F to 104°F).
The motion of the aneroid capsule is transmitted to the axle of the pointer by driving a segment and wheel with an excellent fine finish of the gearing. All bearings have an excellent fine finish. The Instruments have only got a minimum of idle friction because of the advantageous shape of the levers and bearings.
Case in polished or chromed brass, diameter 165 mm.
Mineral glass cover.

"Fischer aneroid from Germany, with a 5.5" dial and a 5-cell movement is among the best of the aneroids available today. This instrument has an accuracy of better than +|-0.7 mb over its full working range of 890 to 1050 mb. Fischer aneroids have been used at sea for 60 years." David F. Burch, PhD, Director of the Starpath School of Navigation, Seattle, WA USA
