Vintage Chrome & Wood Surround SB Rototherm Thermometer. In The Shape Of A Ships Wheel, it dates to about the 1940s. It has a lovely large face, with an easy to read dial showing the ‘freezing point’ temperature of 32 ºF, and measures from -20 to 140 ºF.

A ‘must have’ item for the vintage office. It measures temperature in Fahrenheit and is encased in a wood surround with a round wood base, allowing it to display nicely on an office desk or mantelpiece.

Bimetallic Thermometer

Rototherm invented the bimetallic thermometer in 1934. The thermometer has a metal pointer that moves up and down a circular scale. The pointer is mounted on a coiled piece of metal called a bimetallic strip. The hotter the temperature, the more the bimetallic strip expands, and the more it pushes the pointer up the scale.
