Tendency Barometer Admiral Fitzroy Storm Glass Hygrometer Historical Weather Instrument

A rather remarkable piece of equipment. Though it's quite attractive it's also completely functional and provides entirely accurate data. It's the real thing and clearly intended for those of us who wouldn't even consider hanging a replica rifle over our fireplace. It comes with a calibration kit and very simple instructions for adjusting the barometer to local elevation and calibration of the hygrometer. The storm glass is quite fascinating. It's larger than it appears in the photo and very easy to examine crystal behavior. It's been pretty rainy here of late and I noticed that within hours of arrival the storm glass became quite cloudy with suspended crystals near the top with sparkles suspended below. Pretty neat! Glad I spent the money for it, hung it in my living room and wouldn't hesitate to recommend it to others. The only drawback.... I've spent quite a bit of time since it arrived, standing, facing the wall, staring at it. Wife doesn't seem to mind though.

The instrument itself is beautiful. I was disappointed to learn that the storm glass is not really functional, it takes a lot away from the overall purchase.

Instructions not clear for settings, not designed well for easy of access to make calibration adjustments. You have to remove the entire assembly from the wall, take the back panel off to acccess the instruments for calibration. It should have been designed with a hinged door accessing the instruments after they are mounted especially as expensive as this weather instrument is.
