Pierre Monti Torino - Thermometer - Wood, Glass

Rare and interesting folding travel thermometer with a hinged protective wooden case An antique collectible from the mid-nineteenth century, as suggested by the date "Paris 1850" inscribed on the scale. This is an interesting piece because it features two temperature scales side by side: the Centigrade (or Celsius) scale on the left and the Réaumur scale on the right. The latter, developed by René Antoine Ferchault de Réaumur in the early eighteenth century, was once widespread in Europe before being replaced by the Celsius system. On the top, the manufacturer's signature is visible, "Pierre Monti a Torino" (maker of optical and precision instruments active in Turin in the nineteenth century). The plaque bears the classic thermometric annotations of the period. Ink handwriting / pyrographed inscription clearly legible. Original and functioning glass column (without bubbles or interruptions in the liquid) - The thin tube in the center with the lower bulb encloses the liquid thermometer (colored alcohol). Wood finish free of cracks.
