Set of three vintage precision analog pressure gauges manufactured by Carlo Erba, a historic Italian brand internationally recognized for scientific, medical, and industrial instrumentation. Produced in the mid-20th century, these gauges represent classic Italian engineering focused on reliability, accuracy, and long-term durability. DESCRIPTION This set consists of three original Carlo Erba analog manometers with a compact 40 mm case diameter, dating to the mid-20th century (circa 1950s–1970s). Two gauges feature a measurement scale of 0–3 kg/cm², while one gauge features a 0–5 kg/cm² scale. The instruments are constructed with metal cases, internal Bourdon tube mechanisms in brass and bronze, and glass dials. Designed for laboratory and industrial environments, they combine functional precision with a sober, utilitarian aesthetic typical of the period. Carlo Erba instruments were widely used in professional scientific contexts, making surviving functional examples increasingly collectible.
