The Quest Pulse Oximeter is designed to support individuals as they monitor their pulse rate and oxygen saturation. This lightweight portable device takes fast, non-invasive measurements at the fingertip. Ideal for monitoring heart rate and oxygen saturation during sports activities, while exercising or during air travel. Additional features include: • Simple 1-button operation - Hassle-free operation with an illustrated manual for support and guidance • Fast, reliable results - Only seconds needed to achieve measurements. Measurements will change as your pulse rate or oxygen saturation changes. • Multi-view display screen - Large LED color display shows clear readings. With the push of a button the display rotates to allow measurements to be read from multiple angles. • Audible alerts - Alarms will sound if measurement levels fall below or rise above preset thresholds. • Comfortable and form fitting cushion • Automatic power on/off and low battery indicator • Pulse rate graph - This waveform graph helps indicate the reliability of the readings. A smooth and regular waveform represents good signal quality and therefore a more reliable reading. Includes: pulse oximeter, 2 AAA batteries, lanyard, storage pouch and user manual, 2 year limited warranty.
