CMS50EL Fingertip Pulse Oximeter | Rechargeable SpO2 Monitor with LED Display #

Fingertip pulse oximeter with LED display, SpO2 and pulse rate monitoring, bar graph, auto power-off, and rechargeable battery. Portable oxygen monitor for home, sports, and clinical use.

The CONTEC CMS50EL Fingertip Pulse Oximeter is a portable, non-invasive device designed for fast and accurate measurement of blood oxygen saturation (SpO₂) and pulse rate (PR). Adopting Photoelectric Oxyhemoglobin Inspection Technology integrated with Capacity Pulse Scanning & Recording Technology, this compact oximeter delivers reliable results through the fingertip in seconds.

Featuring a clear LED display with SpO₂ value, pulse rate value, and bar graph indication, the CMS50EL provides easy-to-read measurements at a glance. With a rechargeable lithium battery, automatic power-off function, and low-voltage indication, this device is designed for user convenience and long-lasting performance.

Ideal for home healthcare, hospitals, oxygen bars, community health services, and sports physical care. Can be used before or after physical activity—not recommended for use during exercise.

Key Features

🩸 Accurate SpO₂ & Pulse Rate Monitoring

The CMS50EL provides precise measurement of blood oxygen saturation (SpO₂) and pulse rate (PR) through the fingertip.

• SpO₂ Measuring Range: 0%–100% (resolution 1%)

• SpO₂ Accuracy: ±2% (70%–100%); below 70% unspecified

• Pulse Rate Range: 30–250 bpm (resolution 1 bpm)

• Pulse Rate Accuracy: ±2 bpm or ±2% (whichever is greater)

🖥️ Clear LED Display

The LED display ensures clear, easy-to-read measurements in any lighting condition.

📊 Comprehensive Display Information

The CMS50EL screen shows all essential data at a glance:

• SpO₂ value – Blood oxygen saturation percentage

• Pulse rate value – Heart rate in beats per minute

• Bar graph – Visual pulse strength indicator

🔋 Rechargeable Lithium Battery

The CMS50EL is powered by a 3.7V rechargeable lithium battery:

• Battery life: Up to 20 hours of continuous operation

• Charge cycles: No less than 300 charge/discharge cycles

• Charging accessories: Includes data cable and power adapter

⚡ Automatic Power-Off Function

The device features intelligent power management:

• Automatically powers off within 5 seconds when the finger is removed from the probe

• Preserves battery life and ensures the device is always ready when you need it

⚠️ Low-Voltage Indication

A low-voltage indicator appears before the battery voltage becomes too low for normal operation, alerting you to charge the device before it becomes inoperable.

💪 Performance in Challenging Conditions

• Weak filling performance: SpO₂ and pulse rate can be shown correctly when pulse-filling ratio is 0.4%

• Light resistance: Deviation between measurements in artificial/indoor natural light and darkroom conditions is less than ±1%

📱 Compact & Lightweight Design

• Dimensions: 57(L) × 32(W) × 30(H) mm

• Weight: Approximately 50g (including battery)

• Small in volume, light in weight – convenient for carrying

• Simple operation – easy to use

• Low power consumption – less than 30mA
