Cryo Sentinel®

World’s ONLY Early Warning System For Cryogenic Dewar Vacuum Failures

State-of-the-Art Cryo Storage Early Warning System.

CryoSentinel® monitors the exterior temperature of your cryogenic Dewars, detecting the external drop in temperature caused by vacuum loss and alerting you immediately. This patent pending process gives you extra precious time and live video information wherever you are to help you save your most valuable assets.

Super Powers!

Infra red technology allows you to see the health of your cryogenic dewars in an instant. As vacuum is compromised the external Dewar wall cools and can be clearly seen with Cryo Sentinel.

See the health of cryo storage anywhere in the world in an instant


Sleep better at night.

With Cryo Sentinel’s live thermographic video, and streaming around the world, you will always know that your cryo storage is safe. A quick look at your computer or phone will let you sleep better at night knowing that all your dewars are working as they should.

Infra red technology

See into the future!

Cryo Sentinel allows you to see your cryo storage in a completely new light (infra red!). This allows you to see things like slow vacuum failure, so you can take action to safe your samples from a Dewar before it fails. If this happens to you, you will be glad you had Cryo Sentinel.

Choose your system

CryoSentinel can work independently as an early warning system in addition to your current monitoring system or expand the features of your current monitoring system via an alarm out port. It is also available as a passive thermographic video only version.

There are

2 models

available to meet your needs from a video only unit to an active early warning system.

We would love to talk to you about how Cryo Sentinel can be added to your monitoring solution.


Cryosentinel uses thermal imaging technology and an array of sensors to monitor your dewars and cryogenic vessels and will immediately alert you in the event of a vacuum failure.
