These factory installed systems monitor CO2 or N2 pressure in source tanks. These systems are designed to automatically switch from one cylinder to another when supply in the first tank is exhausted (pressure falls below 15 PSI). Audible and visual alarms on the incubator control panel alert the user to tank switch-overs, and to when both tanks are low. The need to frequently change out cylinders is minimized, and the risk of running out of gas reduced.
Fitting unobstrusively inside the incubator's casing; these systems interface directly with unit power supply and control systems.
