The CMS50N Pulse Oximeter is a reliable, portable device designed for non-invasive measurement of blood oxygen saturation (SpO₂) and pulse rate through the fingertip. Built with advanced photoelectric sensing technology, it ensures fast and precise readings suitable for hospitals, clinics, and homecare use. The device features clear SpO₂ and pulse rate displays, along with pulse rate waveform and bar graph visualization for easy interpretation. Its screen brightness can be adjusted for comfortable viewing, and users can optionally change the display mode for convenience. The CMS50N also includes low battery voltage indication and an automatic standby function that helps conserve power. Compact and easy to operate, it offers a practical solution for continuous or spot-check monitoring of oxygen levels.
