Product description

As Precise as Specialized Medical Apparatus

More Accurate & Durable

This pulse oximeter uses medical-grade sensors and chips, providing measurement results consistent with those of professional instruments used in hospitals. Additionally, this pulse oximeter fingertip is made from advanced materials and manufacturing processes. It has undergone numerous tests, including high drops and repeated water immersion, and still functions properly.

Seeing is Believing

Please refer to the comparison demonstration with professional medical testing instruments and the destructive testing demonstration in the introduction video of this pulse oximeter on the Webpage.

Industrial-Grade Reliability

This oximeter is manufactured using industrial-grade materials and processes, ensuring exceptional durability. It has been tested for resilience against drops from heights, water immersion, and extreme temperatures, yet it continues to function properly.Please refer to the durability test demonstration video in the introduction video of this oximeter.

Specifications SpO2 Range: 0%-100% SpO2 Accuracy: ±2% Pulse Rate Range: 30bpm-250bpm Pulse Rate Accuracy: ±2bpm Perfusion Index: 0.1% – 10% Display Format: 2-color OLED Display

Continuous Monitoring & One-Key Setup

This pulse oximeter features a special spring-clip design combined with internal medical grade silicone material, ensuring it stays in place.

【ACCURATE】Medical oximeter only requires pulse oximeters to have SpO2 accuracy of ±2%, the A320E fingertip pulse oximeter deviates less than 1% under lab conditions. Upgrade LED and sensor allows SpO2 (Blood Oxygen Saturation level) and pulse rate measurement at low blood perfusion index. Plethysmograph and Perfusion Index can help you to judge whether your measured SpO2 and Pulse Rate is properly.
【RELIABLE】From the ABS shell, OLED screen, acrylic panel, high-speed computing chips , anti-skip silicone inside, medical-grade silicone finger mold and various electronic components of oxygen finger monitor, all adopt high-quality materials and components. Even the spring of the oximeter finger has been subjected to thousands of tests. We will never use any cheap material to make oxygen monitor.
【24 MOTHS WARRANTY】24 months of manufacturer warranty. If the product has quality problems, please contact the seller for free replacement via Amazon Mail.
【Bright OLED Screen】The large Dual-Color OLED screen is large and bright, you can read SpO2 and pulse rate clearly even in strong sunlight. The finger oximeter designed for sports or aviation use like mountain climbers, skiers, bikers or people interested in measuring their SpO2 and pulse rate. Oximeter finger chamber with smart spring system, accommodates wide range of finger sizes – children over one year old to adult.
【Easy to use】Alarm function-Auditory alarm to warn you when your SpO2 and Pulse Rate are beyond set limits. The pulse oximeter fingertip automatically turns off 6-8 seconds. Include 2X AAA BATTERIES that you can use the pulse oximeter right out of the box, a Carrying Case to protect the finger oximeter from damage and dirt, a LANYARD for convenience.
