## Description

## How it fits

For a quick check at home or while travelling, the Keanor BSX251 brings blood oxygen saturation and pulse rate readings together in a compact finger monitor. Its one-button operation keeps the process straightforward, and readings are displayed in about 8 seconds. The monitor is designed for adults and children, making it practical to keep on hand for individual or family use.

A large-font LCD screen rotates automatically through 360°, so the result can be read in different orientations. The finger chamber has a latex-free silicone interior with a non-slip surface for a secure, comfortable fit during a reading.

## Pros

This monitor tracks SpO2 and pulse rate, with Perfusion Index (PI) monitoring to show signal strength. Customizable alert limits for oxygen and pulse rates let you set the thresholds that suit your monitoring routine. These features make it more informative than a simple oxygen-only display, while keeping operation to a single button.

The bright, large-font screen is designed to make readings easier to see, including when helping another person check their levels. Automatic screen rotation supports different viewing angles without requiring you to reposition the display manually. Its portable format also suits keeping a monitor nearby at home or taking it along for activities such as hiking or a gym visit.
