Contec Finger Digital Pulse Oximeter

The CONTEC Finger Digital Pulse Oximeter – CMS50D, available at Tabib Mart, is a high-function device designed for accurate fingertip measurement of oxygen saturation (SpO₂) and pulse rate. Featuring a compact clip-on design, the instrument offers a dual-colour display (blue/yellow) or OLED variant on some models, a readable bar graph and waveform display, and reliable performance across a wide measurement range.

Built with simplicity in mind, the CMS50D works with two AAA alkaline batteries and includes low-voltage warning and automatic shut-off when the finger is removed. The measurement range of 0 %-100 % SpO₂ and 30-250 bpm for pulse rate (with resolution of 1 % for SpO₂ and 1 bpm for pulse) ensures its suitability for both home monitoring and light clinical use.

The device is particularly useful for respiratory, fitness, sleep and outpatient monitoring contexts: whether tracking oxygen saturation during exercise, monitoring a patient’s baseline at home, or providing a secondary check in a clinic. With its lightweight build (~50 g including batteries) and portable dimensions (~57 × 31 × 32 mm), it fits easily into a pocket or bag.

Moreover, the CMS50D performs well under low perfusion and ambient light conditions: the manufacturer states correct readings can be shown when pulse-filling ratio is 0.4%, and deviation due to ambient lighting is less than ±1 %. Safety reminders apply: this device is not suitable as a sole monitoring tool in critical care, does not provide alarms for hypoxia, and should not replace professional medical evaluation.

For anyone seeking a reliable, portable fingertip oximeter with clear display, solid accuracy and user-friendly design, this model from CONTEC stands out as a cost-effective choice. Tabib Mart makes it easily available for purchasing in Egypt and beyond.
