Low gas alert No Repeating visual and audible alerts for low content* DISS connection outlet flows Up to 100 L/min Up to 200 L/min Available gases Gauge Manometer Digital (with shroud protection) * Please note that ambient and background noise may affect the alert’s audibility. Hearing impairments may also affect an individual’s ability to detect the alert. The visual display on the digital gauge (rather than the sound alert which is set at particular intervals) provides the primary and real time method to determine the amount of medical oxygen remaining by displaying: (1) the pressure bar graph, (2) the volume of gas in liters and (3) the time remaining calculation when the cylinder is in use.
