A hypoxic guard rotameter is a compact gear mechanism that ensures a minimum oxygen concentration of 25% in a gas mixture. It can be used to raise the concentration from 25% to 100%. Hypoxic guard rotameter is precisely manufactured by using superior quality materials
and advance technologies. It’s used in anesthesia machines to measure the flow of gases like oxygen, nitrous oxide etc. The rotameter is also known as a flowmeter, and is a variable orifice, constant pressure flowmeter.
