Portable, pressurized Cryogenic Liquid Dewars are essential for supplying liquid or gaseous nitrogen, argon and carbon dioxide for many laboratory processes. But when it comes to monitoring its contents, the float gauges traditionally found on these dewars are prone to inaccuracy or failure, which can often leave you feeling unsure about how much liquid is available to supply your applications. To avoid the uncertainty of low gas and liquids levels during critical processes, many labs return dewars with as much as twenty percent unused product.

Available exclusively from Linde, the StarWatch ™ Cryogenic Monitoring System provides a clear, digital read-out of the liquid level and pressure in the dewar and alerts users with an audio and visual alarm when supply is running low. Compared to conventional float gauges, the capacitance-based level measurement of the StarWatch system provides enhanced reliability and accuracy.  

The StarWatch system comes installed on Linde’s ProSpec™ cryogenic dewars – ready for use. Armed with the StarWatch system’s accurate level and pressure reporting, a ProSpec cryogenic dewar allows you to stay focused on your work, avoiding process and application interruptions from product outages and minimizing the return of unused, residual liquid.
