Description
Product Overview
The AccuMed CMS-50D1 Fingertip Pulse Oximeter is engineered to provide precise blood oxygen saturation (SpO2) and pulse rate measurements in a compact, user‑friendly package. Constructed from high‑impact ABS plastic, the device is designed to withstand the rigors of daily transport, whether it is tossed into a gym bag, a backpack, or a travel case. Its 2.0‑inch LED display rotates automatically to match the orientation of the user’s hand, delivering crystal‑clear readings in both portrait and landscape modes. The oximeter operates on two standard AAA batteries, delivering up to 20 continuous hours of operation before an automatic power‑off conserves energy when not in use. With a weight of only 50 grams (1.76 ounces) and dimensions of 3 × 1 × 2 inches, it is truly portable, making it an ideal companion for athletes, pilots, hikers, and anyone who needs to monitor oxygen levels on the move.
Technical specifications include a measurement range of 0–100% SpO2, a pulse rate range of 30–250 bpm, and an accuracy of ±2% for SpO2 and ±3 bpm for pulse rate. The device complies with FCC regulations and is CE marked, ensuring it meets international safety standards. Although it is not intended for medical diagnosis, the oximeter provides reliable data for personal health tracking, fitness optimization, and altitude acclimatization.

Usage
Designed for versatility, the CMS‑50D1 can be used in a variety of environments. Athletes benefit from real‑time oxygen monitoring during high‑intensity training sessions, allowing them to adjust effort levels and recovery periods for optimal performance. Pilots and frequent flyers appreciate the ability to check oxygen saturation during long flights, especially at higher altitudes where cabin pressure changes can affect breathing. Outdoor enthusiasts, such as hikers and climbers, find the device indispensable for altitude acclimatization, ensuring they remain within safe SpO2 thresholds while trekking in mountainous regions.
Because the oximeter is fingertip‑sized, it accommodates users from children over four years old to adults, making it suitable for family use. The included lanyard enables hands‑free wear, while the durable travel case protects the device from scratches and impacts when stored in a pocket or bag. Its quick one‑second reading time ensures that users can obtain measurements without interrupting their activities.
