Thermograph by Townson Mercer of London c.1900

Another unusual thermograph in an oak case with glass panels to the front & rear with a metal grill to the non-hinged side with a brass carry handle to the oak top, complete with original ink bottle. Made circa 1900 by Townson Mercer of London. The movement is based on a rather attractive bi-metallic strip in a quadrant format & works very well for its age.

The temperature range is 0’-100’ Fahrenheit & a quantity of weekly charts will be supplied together with a fresh bottle of ink.
