Key Features

🩸 Accurate SpO₂ & Pulse Rate Monitoring

The CMS50DA provides precise measurement of blood oxygen saturation (SpO₂) and pulse rate (PR) through the fingertip. The device uses two wavelengths of light transmitted through the finger to deliver quick, non-invasive readings in under 10 seconds.

• SpO₂ Measuring Range: 0%–100%

• Pulse Rate Range: 30–240 bpm

• High accuracy for reliable clinical and home use

🖥️ Dual-Color OLED Display

The high-quality dual-color OLED screen delivers crisp, vibrant visuals with excellent contrast. Unlike traditional LCDs, OLED technology provides:

• Superior visibility in both bright and dim conditions

• Wide viewing angles for easy reading

• Low power consumption for extended battery life

🔄 6 Display Modes & 4-Direction Adjustment

The CMS50DA offers 6 display modes and 4-direction display adjustment, allowing you to view measurements from any angle. Whether you're checking your own oxygen level or monitoring a patient, the screen adapts to your viewing preference.

💡 Adjustable Brightness with 6 Levels

The screen brightness is adjustable with 6 levels of brightness, ensuring clear visibility in both bright daylight and dim environments.

📊 Perfusion Index (PI) Monitoring

The CMS50DA includes perfusion index (PI) monitoring, providing valuable information about the strength of the pulse signal at the measurement site—an important indicator for assessing measurement reliability.
