With a two color screen and six display modes the C21R Fingertip Pulse Oximeter is a convenient, compact and reliable device for non-invasive spot-checks of oxygen saturation levels (SpO2). The C21R's lightweight and compact design accommodates a wide range of finger sizes -- from pediatric to adult -- and includes the latest oximetry technology.
Small, Lightweight, Durable & Accurate: The C21R Fingertip Pulse Oximeter is very durable and provides accurate, simple measurements to give you the peace of mind you need that your oxygen levels are safe during rest and activity.
Informative High Resolution Display: C21R features a high resolution, two color display with information on SpO2 Pulse Rate, a Pulse Intensity Bar Graph, Current Battery Capacity, and a Pleth Waveform.
Battery Operated Power Miser: The C21R comes complete with two AAA batteries. To conserve power the display automatically powers off if a finger is not inserted into the device for 8 seconds; but C21 is energy efficient so it can work continuously for more than 24-hours. If you need to change the orientation of the display it is easy with a short press of the power button; in addition the display has 10 brightness settings and 6 display modes for convenient viewing in a variety of lighting and usage conditions.
