This vintage industrial pyrometer indicator was manufactured by Electroflo Meters Co. Ltd. and assembled in South Africa. Designed for measuring high temperatures up to 1,000°C ($^\circ\text{C} \times 100$), this heavy-duty analogue instrument features a curved glass viewing window, an aged brass-tone temperature arc, manual zero adjustment controls, and original battery terminal connections at the base. Founded in the UK during the early 20th century, Electroflo was a prominent manufacturer of industrial measurement and control systems, supplying power plants, foundries, and manufacturing facilities worldwide with robust monitoring equipment.Housed in a rugged black cast-metal casing with authentic wear, patina, and chipped paint that highlights its rich industrial history, this unit serves as a striking display piece for collectors of scientific instruments, vintage technology, or steampunk decor.Dimensions: 28cm (l) x 17cm (w) x 26.5cm (h)
