DescriptionPulse Oximeter is a portable equipment adopting advanced technology, it mainly checks SpO2 and PR value through the finger, which provides advanced, non-invasive and scientific means for quantitative measurement of oxygen saturation. Pulse Oximeter is applicable for use in plateau area, community healthcare, oxygen bar, Fitness clubs, physical training room, family and medical institution, etc.Features- Color: Black.- Material: Plastic.- Size: 5.5 x 3.6 x 3.8 cm/2.2 x 1.4 x 1.5 inch.- Battery: 2xAAA battery (not included).- Screen resolution: 128x64.- Display mode: 0.96 inch dual color OLED display (blue and yellow).- Sp02 measuring range: 0%-100% (1% resolution).- Accuracy: 2% or 2bpm.- PR measuring range: 30bpm-250bpm (1bpm resolution).- Voltage: DC 3V.- Power consumption: 30mA.- Pulse oximeter mainly measure human oxygen saturation and pulse rate. It is suitable for family, physical care in sports and etc. What's more, it also suits for elderly people over 60 years old, people who work more than 12 hours a day.- Turn the Pulse Oximeter on, put one of your fingers into rubber hole of the oximeter.
