Come and see our amazing products. The 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 one more critically acclaimed feature, Perfusion Index (PI), that will improve the reliability of the readings dramatically. 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. Using a vastly improved sensor, this pulse oximeter can also now correct for small movements, allowing more versatile usage. Please note that this is not a medical device. Intended use for spot check of blood oxygen saturation level at home. Pls confirm with us about the packing info, stock status and exact production time before placing your orders.
