Protekt Finger Pulse Oximeter, SpO2 & Pulse
Protekt Finger Pulse Oximeter — SpO2 & Pulse Rate, Digital Display
Overview
The Protekt Finger Pulse Oximeter is a quick, easy way to check your blood oxygen saturation (SpO2) and pulse rate right at your fingertip. Slip your finger inside, press the button, and a painless infrared reading does the rest — results appear in seconds on the built-in digital display, complete with a heart-rate bar graph. It's completely non-invasive and simple enough for anyone to use.
Compact and light at just 2.1 ounces, it slips into a pocket or bag and is handy at home, during exercise, or for sports and high-altitude activities where you want to see how your body is responding. It runs on two AAA batteries (included) for more than 30 hours of use, and an automatic power-off preserves battery life when you're finished. The unit reads SpO2 from 70–100% and pulse rate from 30–240 bpm.

Equipment Specialist Insight: A fingertip oximeter is one of the simplest wellness tools to keep on hand — slip it on, hold still for a few seconds, and you'll see your oxygen saturation and pulse. A few tips make readings more reliable: warm hands read better than cold ones, staying still matters (motion throws the number off), and it helps to remove nail polish and rest your hand on a table. Keep in mind it's a spot-check device rather than continuous monitoring, and it sips battery thanks to the auto power-off — though a spare set of AAAs is always worth having. For fitness or altitude, it's a handy way to see how your body is responding in the moment.
