CONTEC CMS50D Medical Finger Pulse Oximeter

The CONTEC CMS50D finger pulse oximeter is a high-quality device that meets CE certificate compliance standards and medical standards. The oximeter can monitor not only heart rate (pulse) but also blood oxygen saturation.

The device is small and portable, as well as comfortable and easy to use thanks to its clear display, which features 6 display modes with bar and line graphs. The oximeter also has an automatic shutdown function 5 seconds after removal from the finger, preventing unnecessary battery consumption. When battery replacement is needed, the device indicates this with a low voltage warning, allowing timely replacement and avoiding issues related to low battery.

The CONTEC CMS50D finger pulse oximeter complies with the required medical device standards, confirmed by the manufacturer's declaration of conformity and the CE certificate issued by TÜV SÜD PRODUCT SERVICE GMBH.
