CMS50M Fingertip Pulse Oximeter | Portable SpO2 Monitor with LED Display & Auto Shut-Off #

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

The CONTEC CMS50M 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 CMS50M provides easy-to-read measurements at a glance. With automatic shut-off, low-battery indication, and soft silicone fingertip clip for comfortable wear, this device is designed for user convenience and long-lasting performance.

Ideal for home healthcare, hospitals, oxygen bars, community health services, plateau areas, 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 CMS50M 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 with Bar Graph

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

⚡ Automatic Shut-Off & Auto Standby

The device features intelligent power management:

• Automatically powers off after 5 seconds when no signal is detected

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

🔋 Low-Battery Indication

A low-battery indicator appears when the battery voltage is too low to work, alerting you to replace batteries before the device becomes inoperable.

💪 Performance in Challenging Conditions

• Weak filling performance: SpO₂ and pulse rate can be shown correctly when pulse-filling ratio is 0.4%. SpO₂ error is ±4%, pulse rate error is ±2 bpm or ±2%

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

📱 Compact & Lightweight Design

• Weight: Approximately 50g (with batteries)

• Dimensions: 60mm(L) × 34mm(W) × 33mm(H)

• Soft silicone fingertip clip – comfortable for a wide range of finger sizes

• Low power consumption – working current ≤25mA

• Easy to use – simply place your finger in the testing chamber
