StarWatch™

Praxair’s StarWatch™ Cryogenic Monitoring System

You rely on portable, pressurized cryogenic liquid dewars to supply liquid or gaseous nitrogen, monitoring systemargon, and carbon dioxide to your lab. The float gauges traditionally found on these dewars are prone to inaccuracy or failure, leaving users uncertain about how much liquid is available to supply their applications. To avoid untimely product outage, many labs return dewars with as much as 20 percent unused product, wasting money and decreasing productivity.

The StarWatch™ Cryogenic Monitoring System – available exclusively from Praxair – provides a clear digital read-out of the liquid level and pressure in your dewar and alerts you with an audio and visual alarm when your supply runs low. The capacitance-based measurement of the StarWatch™ system provides a leap forward in reliability and accuracy versus conventional float gauges.

The StarWatch™ system comes equipped on Praxair’s ProSpec™ cryogenic dewars – high quality liquid packages dedicated to laboratory applications and optimized for either low (liquid) or high (gas) pressure service. The reliable ProSpec dewar, combined with the StarWatch™ system’s accurate level and pressure reporting, allows you to stay focused on your work, avoiding process interruptions from product outages, and the waste associated with residual returns.
