The finger oxygen monitor may be used to assess pulse rate at any time in homes, hospitals, and social institutions. - : The 2 AAA batteries allow the fingertip pulse oximeter to collect 600 measurements. When the measurement results exceed the user-set PR limitations (upper or lower), the device will inform you with a value flashing prompt (with screen flickering) to draw your attention. You may either place it in the luggage or hang it around your neck or wrist using the included lanyard. : Our oxygen finger monitor has one-button functionality which makes it straightforward and simple to use.
