Liquid level ruler can measure the liquid level of liquid nitrogen tank manually. When users do not have liquid level measurement device, liquid level ruler is also convenient and helpful to know the level of tanks. Liquid level ruler can check the remaining amount of the liquid nitrogen tank.

First, wear necessary cryogenic protection such as cryo-gloves, cryo-apron, and then insert the liquid level ruler into the bottom of the liquid nitrogen tank and let it stand for about 30 seconds. Then take out the ruler, and the frosting position is the height of the liquid nitrogen remaining in the liquid nitrogen tank. Do not insert with a hollow tube to prevent the liquid nitrogen from rushing out of the tube and causing splashing.
