Used for pressurising dewars in the transfer of liquid helium or other gases.

Could also be used as helium gas reservoir at cryogenic systems like top loading cryostats with exchange gas area.

Stainless steel construction with a fine rubber diaphragm held in place with an o-ring on the Dipstick Head.

The unit provides accurate indication of liquid helium level depth.

The thermal gradient created in the tube leads to thermal oscillations, which are felt by the vibration of the membrane.

The frequency of the oscillation with the lower end in liquid helium is noticeably lower in comparison to that when in cold gas, allowing the liquid level to be easily determined.

The dipstick should not be left in the dewar when its not in use because it introduces a large amount of heat.

Dipstick will ship with 5 spare membranes.
