Rare vintage Taylor Stormograph recording barometer storm 7-day 110VAC with 3-stage UniMag diaphragm sensor.110VAC Motor turns recording drum (one revolution per week). Writing arm moves as storm comes through.We do not know if it's still calibrated, but it did move significantly (down) when the last storm came thru, and came back up in a few days.Will be shipped disassembled (drum cylinder, 3-stage barometric sensor) due to sensitive/fragile components.Instructions for assembly are easy and well documented in the PDF instruction manual.
Eyedropper ink bottle is about 1/3 full, the writing arm triangular nib is empty may need cleaning when re-inking.The ink is viscous so that it won't evaporate. We found re-inking was needed with a drop every couple of weeks into the nib.
We used xeroxed charts over the years, but we see that some are still on the market incl .We will include the old UniMag 3-stage sensor for thoroughness.
A great learning experience for kids, and a refreshing break from the digital world to become more connected with our changing atmosphere.
When hurricane Bob came thru a few decades ago, the writing arm went to the bottom of the chart almost in a vertical line.
PDF instruction booklet on request.The outstanding feature of the Weather-HawkSTORMOSCOPE Barometer is its adaptation of theUNI/MAG movement (UNIversal altitude range/MAGnified pointer motion), an exclusive developmentby Taylor, leader in this industry since 1851.Three of the new UNI/MAG capsules are stackedto make up the temperature compensated movement.Pen motion for a given barometric pressurechange is increased by 50%. Threshold sensitivite,hysteresis error and dead band have been reducedso there is practically no observable lag in reversalof pen motion as a pressure change occurs. A newpen arm is provided to reduce pen pressure.The small pressure changes which are so vitallyimportant in making local forecasts of comingweather are readily apparent on the chart. Inareas where the changes are normally small inmagnitude, and not particularly obvious on the oldstyle recording barometer chart, the trace providedby the new movement makes them easily readable.
