The CMS50D Pulse Oximeter is a reliable and easy-to-use device designed for precise measurement of blood oxygen saturation (SpO₂) and pulse rate through the fingertip. Utilizing advanced photoelectric sensing technology, it provides fast and accurate readings suitable for hospitals, clinics, homecare, and fitness applications. The device features a clear display that shows SpO₂, pulse rate, pulse waveform, and a bar graph for pulse strength visualization. It also includes automatic direction adjustment for flexible viewing and adjustable screen brightness for optimal visibility. The CMS50D conserves power with an automatic standby function and provides a low-voltage warning to ensure consistent operation. Its small size, lightweight design, and simple one-button interface make it ideal for both professional and personal use.
