The Innovo Deluxe Fingertip pulse oximeter shows your measured SpO2 and Pulse Rate on a high quality OLED screen (with six multidirectional display choices) and come with two critically acclaimed features, the Plethysmograph and Perfusion Index (PI), that will improve the reliability of the readings dramatically. The plethysmograph informs you when the pulse oximeter is optimized while the PI conveniently informs you of the strength of your pulse. If the PI value is less than 0.2%, this means that your hands are too cold or improperly positioned in the pulse oximeter. Simply warm your finger and reposition it so that it is right under the LED lights. No more second guessing if the readings are reliable or why the pulse oximeter is not giving a reading. Using a vastly improved sensor, the Innovo deluxe pulse oximeter can also now correct for small movements, allowing more versatile usage. Comes with a lanyard and 2 AAA batteries so that you can use the pulse oximeter right out of the box.
