Key features

• •Fingertip Pulse Oximeter & Blood Oxygen Monitor — SpO2, Heart Rate & Perfusion Index in 5 Seconds: The SimpliCare C101A2 measures blood oxygen saturation (SpO2: 0–100%), pulse rate (30–240 bpm), and perfusion index (PI ≥0.2%) with a fast 5-second response time. A reliable o2 sensor and oxygen monitor for home, fitness, travel, and altitude use — trusted by families, athletes, hikers, and nursing school students alike.
• •Pulse Ox with Real-Time Plethysmograph Waveform & PI — More Than a Basic Oximeter Finger Reading: Unlike basic finger pulse oximeters, the C101A2 displays a real-time plethysmograph waveform and numerical perfusion index (PI) to confirm signal stability and correct finger placement — giving you confidence in every reading. A true spo2 pulse oximeter for users who want more than just a number.
• •Bright Multicolor OLED Display with 4-Way Rotation — Clear in Any Lighting: The high-contrast OLED oxygen meter display shows SpO2, pulse rate, PI, waveform, and battery level clearly in any lighting — daylight, indoors, or at night. 4-directional display rotation means you always read results at the most comfortable angle, whichever way you hold it. No squinting, no guessing.
• •Finger Oxygen Monitor with 40-Hour Battery Life & Auto Shut-Off: Powered by 2×AAA batteries (included) with up to 40 hours of continuous use — among the longest battery life of any finger oxygen monitor in its class. The 8-second auto shut-off preserves battery between readings, so this oximeter finger with pulse tracking is always ready when you need it.
• •O2 Pulse Oximeter Finger for Home, Fitness, Travel & Altitude Use: Whether you are monitoring oxygen levels at home, tracking recovery after workouts, checking saturation at high altitude, or completing nursing school coursework, this compact o2 pulse oximeter finger fits seamlessly into daily life. Lightweight at just 35g (without batteries) and small enough for any pocket or bag.
