Tycos Industrial Thermometer

<< >>
This is a short-stem instrument designed for industrial use. The brass V-shaped case is marked “Tycos” at top, and “Taylor / Instrument / Co.” at bottom. The black housing around the mercury-in-glass thermometer with a milk glass tube has a scale from 32 to 240 degrees Fahrenheit, and is marked “Tycos / ROCHESTER / N.Y. U.S.A.”
Hohmann & Maurer had been making instruments of this sort since the mid-1880s, and continued doing so after being bought out by Taylor Bros. in 1896. This example was made after 1908 when the Taylor Instrument Co. introduced the Tycos trade mark and dropped the Hohmann & Maurer signature and trade mark. It came to the Smithsonian in 1923.
