Designed for Everyday Mobility

The KFO4 focuses on portability and convenient daily use. With a compact size of 57mm × 30mm × 31mm and a lightweight body of approximately 28g, the device can easily fit into a pocket, handbag, or medical kit. The rounded housing provides a comfortable holding experience, while the side operation button allows users to complete measurements with simple one-hand operation. Whether used at home, during outdoor activities, or while traveling, this portable finger pulse oximeter with LED display provides a practical solution for personal health checks.

Simple Operation Process

The KFO4 is designed to reduce complicated operation steps. Users only need to place their finger inside the measuring clip and press the button to start the measurement process. The optical sensing system collects fingertip data and displays SpO₂, pulse rate, and perfusion index within approximately 8 seconds. The straightforward operation makes it suitable for different user groups, including families, elderly users, and individuals who require regular monitoring.

Stable Data Presentation

The KFO4 adopts a 30mm × 20mm LED backlit display, allowing users to view measurement results clearly in different lighting environments. The horizontal flip display function automatically adjusts the viewing direction according to the user's hand position, improving reading convenience. The screen presents oxygen saturation, pulse rate, perfusion index, and pulse bar information together, helping users understand measurement conditions more completely.

Health Monitoring Applications

The KFO4 is suitable for various daily monitoring scenarios where quick fingertip measurements are needed. It can be used for routine family health checks, exercise recovery monitoring, travel health preparation, and personal wellness management. As a portable finger pulse oximeter with LED display, it provides users with an easy way to obtain essential physiological information without complicated procedures or professional operation skills.

Performance and Reliability

Using optical measurement technology, the KFO4 provides stable measurement performance with an SpO₂ accuracy of ±2% (70%–99%) and pulse rate accuracy of ±3 bpm. The device supports measurement ranges of SpO₂ from 0% to 99%, pulse rate from 25 bpm to 250 bpm, and perfusion index from 0.1% to 20%. Its automatic power-off function helps reduce unnecessary battery consumption during daily use.

Frequently Asked Questions

Q1: Can the KFO4 be used outside the home?

Yes. The KFO4 is designed for portable health monitoring. Its compact size and lightweight structure make it convenient for carrying during travel, outdoor activities, and daily routines. Users can quickly check oxygen saturation and pulse information whenever needed.

Q2: What information can be viewed during measurement?

The portable finger pulse oximeter with LED display displays multiple parameters including blood oxygen saturation (SpO₂), pulse rate (PR), and perfusion index (PI). It also provides a pulse bar graph to show signal strength, allowing users to understand measurement status more clearly.

Q3: Does the device require professional training to operate?

No. The KFO4 uses a simple fingertip measurement method. After inserting the finger and starting the device, users can obtain readings automatically through the optical sensing system without complicated setup or professional operation.

Q4: How does the KFO4 help save battery power?

The device includes an automatic shutdown function that turns off approximately 8–10 seconds after the finger is removed. It is powered by two AAA batteries and provides around 120 minutes of continuous measurement, making it suitable for regular daily use.
