👉 The term "monometer" refers to a device used in physics and chemistry for measuring the pressure of gases. It is commonly used in laboratory settings, particularly in gas chromatography (GC) systems, where it helps to determine the specific gravity or density of a sample by comparing its volume with that of a known reference gas. The monometer is essentially an instrument that allows one to directly measure the pressure exerted on a gas under different conditions, such as at high temperatures and pressures.
