summary:
Use the ordinary
glass plate level meter connecting theory and temperature balance in physics
–far from low temperature ,the temperature is close to the surrording
temperature.equiped proof frost plate to solve frost on the normal glass plate
level meter.in measuring level,low temperature(under 0℃)
medium can frost on the container. It is your best choice.
