【Accurate and reliable】Improved and updated, the 4-Data Pulse Oximeter Fingertip has equipped with advanced sensors that enable accurate measurement of blood oxygen saturation, pulse rate, respiratory rate, and Blood perfusion index. The Pulse Bar and waveform graph (plethysmograph) shows you whether the signal is strong and uniform. The Fingertip Pulse Oximeter accurates results by using a powerful MCU's AI algorithm, which ensures the reliability of the oximeter. 【Unique respiratory rate RR function】The respiration rate monitor computes the respiratory rate in real-time. Using an oximeter with a breathing rate can help you perform breathing exercises and better know your breaths per minute, which is suitable for athletes or people who are interested in this. Ordinary people can also be used as a reference. pulse oximeter with respiration is a good choice. 【Cost-effective】The pulse ox with respiration counter is equipped with a delicate protective bag, IP67-rated for anti-splash and anti-drop protection. Each package includes 1x pulse oximeter, 2 x AAA batteries, 1x protective bag, 2x lanyard, 1x hook, and 1x user manual. It boasts reliable durability under standard workmanship. 【High-definition OLED display 】The oxygen meter finger pulse oximeter presents 4 data parameters on a vivid and high-definition OLED display. The OLED screen features backlight brightness for easy reading even in low-light conditions. 【Ready-to-use】oxygen monitor fingertip can be used directly after being taken out of the box, blood oxygen meter finger is a great gift. The oximetro de oxigeno pulso de dedo automatically enters standby mode after 8 seconds of inactivity to conserve power. This device is intended for sports and aviation use only, not for medical use. The Pulse Oximeter is a non-invasive device intended for spot checking of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). This portable device is indicated for sport and aviation use only, not in clinical institution. not for medical use.
