This simple and classic bakelite thermometer by British manufacturer Rototherm was designed to be either free-standing or wall-hanging. Aimed at the domestic consumer, it was available in a range of colours and was also favoured by manufacturers as an advertising or promotional gift.
This example is in ivory with an off-white dial. It has been fully disassembled, cleaned and polished and is supplied in excellent condition and full working order (the simple bimetallic movement has been adjusted using 20 degrees C as a datum and is sufficiently accurate to give a good indication of temperature (+/- 1 degree) from 10 to 30 degrees C.
