The AccExpert Fingertip Oximeter (ACEXFIOX) is a compact device designed to monitor blood oxygen saturation and heart rate. It uses photoplethysmography, emitting and absorbing infrared light to provide readings of your SpO2 levels and beats per minute on a clear digital screen. Measuring just 60 x 35 x 30 mm, this white device is small enough to be used on a fingertip or other body parts for convenient tracking. It runs on batteries and includes a built-in indicator to let you know when power is low, making it a reliable tool for home monitoring or professional use in clinics and hospitals, especially for those managing respiratory conditions like asthma or COPD.
