CMS50DL2 Fingertip Pulse Oximeter | Portable SpO2 Monitor with LED Display #

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

The CONTEC CMS50DL2 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 CMS50DL2 provides easy-to-read measurements at a glance. With automatic standby function, low power consumption, 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 CMS50DL2 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 Power-On & Standby

The device features intelligent power management for effortless operation:

• Automatic power-on – Simply insert your finger, and the device turns on automatically

• Automatic standby – Automatically enters standby mode when no finger is detected, preserving battery life

🔋 Long Battery Life

Powered by two AAA batteries, the CMS50DL2 can operate continuously for up to 24 hours with low power consumption of less than 25mA.

⚠️ Low-Voltage Indication

A low-voltage indicator appears before the battery voltage becomes too low to work normally, 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% (select larger)

📱 Compact & Lightweight Design

• Dimensions: 60(L) × 32.5(W) × 30.5(H) mm

• Weight: Approximately 50g (including batteries)

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

• Simple operation – easy to use

• Safety Type: Interior Battery, BF Type
