A pressure gauge is an instrument for measuring pressure.
About the Model
Before it was damaged, this pressure gauge was used to measure pressure up to 300 atmospheres. This was owned and used by Karol Olszewski, a professor of chemistry. He was known for his research on gas liquefaction. Liquid gases are unsafe and can easily explode. In December 1894, flammable ethylene was mixed with oxygen and exploded, causing this pressure gauge to explode. Many pioneers of science, such as chemists, physicists, and doctors, frequently risked their lives while conducting research. Manufacturer: Schäffer & Budenberg; Medium: wood, brass, metal, steel
