Vintage Friez Instruments Hygro Thermograph Model 594 Bendix Aviation Corp
Item History & Price
| Reference Number: Avaluer:7487802 |
This listing is for a Hygro Thermograph, recording relative humidity and temperature made by Friez Instruments Division (Bendix Aviation Corp). I am not sure how this thing works, but it seems that it has all the parts and it is in pretty good overall condition. I wound up the cylinder and it has been moving and turning for over a week. It has made more than a full cycle. The pictures tell the story. Quite interesting object.
For inter...national buyers, there is an additional 3 dollar handling charge.
