Noble precision barograph from BARIGO for continuous recording of atmospheric pressure.The machanic barograph has a quartz movement in the solid brass drum, which rotates the drum once a week. A fiber pen attached to the tip of the writing arm records the change in air pressure on a chart paper attached to the drum.The air pressure and its change are measured by four pressure cells mounted one above the other and transferred precisely to the writing arm via a mechanical linkage. The resulting recording curve, the barogram, provides the expert with information about the local weather development, whereby it is not the absolute value of the air pressure that is relevant, but the pressure changes.The hinged case is made of clear lacquered mahogany, the inner parts of polished brass.The scope of delivery includes a yearly set of chart paper and a fiber pen.

This small, classic precision barograph is a piece of jewel and is used for continuous measurement of athmospheric air pressure. It is manufactured in the Schwazwald by the BARIGO company.The machanic barograph has a quartz clockwork in the solid brass drum, which makes the drum rotate once a week. A fiber pen attached to the tip of the writing arm records the change in air pressure on a graph paper attached to the drum. The air pressure and its change is measured by four stacked pressure probes and precisely transferred to the writing arm by a mechanical linkage. The graph created, the barogram, provides the expert with information about the local weather trends, whereby it is not the absolute value of the air pressure that is relevant, but the changes in pressure.The varnished mahogany wood case has a squiggly brass handle and can be opened.Supplied with one year's set of chart paper and one fiber pen.

Diagram paper 210 for the FISCHER precision aneroid barograph 287M / 287MQ.The diagrams are optionally available for theMonthly circulation (13 sheets) - only the FISCHER 287MQ (with quartz clockwork) offers this circulation variantWeekly circulation (60 sheets)Daily circulation (100 sheets)

The replacement pen can be used for almost all drum barographs and can also be used for other writing instruments. The minimum writing period is one year.

Precision aneroid barograph for recording atmospheric air pressure. The measuring element is a 7-fold membrane cell set made of a copper-beryllium alloy, which has proven to be ideal for pressure measurement due to its elastic properties. The vibration-damped mechanical measuring mechanism made of polished brass is ideal for use at sea.Available with mechanical or quartz movement.Ageing, hysteresis and elastic after-effects are practically non-existent with this barograph. A bimetal compensates for the temperature influence on the can set and the transmission system over the entire measuring range from 955 to 1055 hPa and in the temperature range from -30 to +40 °C. All axes of the precision mechanical movement are mounted in jewel bearings, so that the instrument has only minimal static friction.Available with mechanical winding movement (FISCHER 287M) for daily and weekly circulation, changeable. The circulation times are 25.6 h / 176 h.Alternatively with quartz movement (FISCHER 287MQ) for daily, weekly and monthly circulation, changeable. The circulation times are 25.6 h / 176 h / 783 h. The measuring technology is housed in a hinged, mahogany-colored real wood case with brass handle.Technical dataMeasuring accuracy ± 0.7 hPaDiagram graduation 1 hPaHousing dimensions: 345 x 170 x 180 mmWeight: 3.4 kg (287M), or 3.2 kg (287MQ)Scope of deliveryPrecision aneroid barograph FISCHER 287M or FISCHER 287MQ60 chart sheets for the weekly circulation2 fiber tipsDiagram sheets for daily circulation, weekly circulation or monthly circulation are available as accessories.
