Keanor 331 Fingertip Pulse Oximeter with 4-Way OLED Display

For people tracking blood oxygen and pulse rate at home, a fingertip oximeter makes those readings easy to access as part of a regular wellness routine. The Keanor 331 measures SpO2 and pulse rate, with a display that presents both readings alongside pulse and waveform information.

A quick check at home and a portable monitor for the gym or travel call for the same practical features: simple operation and a screen that is easy to read. This model uses one-button operation and a compact fingertip format for straightforward checks in different settings.

Its four-way rotating OLED display helps make the readings visible from different viewing angles. Two AAA batteries and a lanyard are included, so the set is ready for routine use.

Usage tips

Place the oximeter on a fingertip and use the one-button control to take a reading. The screen shows SpO2 and pulse rate in real time, with a pulse bar and plethysmograph waveform for additional visual context. Its rotating display can be viewed from different angles, which is handy when positioning the device for a check or sharing the screen with someone nearby.

For a home wellness routine, it can provide a convenient way to check these two measurements without setting up a larger monitoring device. Its compact format also makes it practical to keep with your gym or travel essentials. The automatic power-off feature helps conserve battery life after use. Buyers commonly describe the readings as quick and the monitor as working as expected, these are individual impressions rather than a substitute for professional medical guidance.

Included in the pack

The set contains one Keanor fingertip pulse oximeter, two AAA batteries and a lanyard. With the batteries supplied, you can get started without sourcing them separately. The lanyard offers a handy way to keep the monitor close during home routines or when moving between activities.

When it makes sense

Choose the Keanor 331 when you want a dedicated device for checking SpO2 and pulse rate, rather than relying on a general wellness accessory that does not show those readings. The OLED screen combines the measurements with a pulse bar and waveform, while one-button operation keeps the process simple. For regular home checks, that means the key readings and their visual indicators are together on one screen, for use away from home, the fingertip design, included batteries and lanyard make it easy to bring along. It is a practical fit for people tracking these measurements during daily wellness routines, sports recovery or oxygen therapy, with the convenience of a compact monitor and a clear, multi-directional display.
