The Model 55 is a self-contained, lightweight, battery operated personal oxygen deficiency monitor. This easy to use monitor does not require any adjustments by the user other than routine calibration. The monitor reads true percent oxygen in the presence of any diluent including humidity and will not be affected appreciably by barometric pressure changes caused by elevation or weather changes.
