This pulse oximeter is durable, so it’ll last for years if you take good care of it. If you don’t use it for 10 seconds, it’ll automatically shut off to preserve the battery. However, even if it runs for 24 hours, it won’t die because it has a fantastic battery life.

HealthTree Pulse Oximeter Blood Oxygen Saturation Monitor
If you’re looking for a budget-friendly pulse oximeter, then this one by HealthTree is the right call.
For the price, you get a unit that’ll be quite precise when monitoring your oxygen saturation levels at night. The device has a sleek, lightweight, modern design. It’s great if you want to use it to monitor your levels at night and carry it around with you.
And since it’s suitable for adult sports enthusiasts, such as hikers, bikers, and those who need to track their oxygen saturation on a daily basis, this unit is extremely versatile.
Although it’s a bit slower, the results will be pretty precise. The display on this pulse oximeter is multicolor, unlike the standard red one, which can hurt some people’s eyes.
Occasionally, however, users have experienced problems reading and understanding the results. For that reason, the manufacturers included an alarm that goes off if your oxygen levels or heart rate are below the normal range.
In addition to oxygen saturation levels and heart rate, this handy pulse oximeter shows the perfusion index, meaning that it will measure your pulse strength.
In case there isn’t enough blood flow in your body, you’ll be able to see it on the device’s display; this kind of feature can warn of any potential heart failures.
Keep in mind that the finger chamber is too big for smaller children. It comes with pre-packed batteries, so you can use it straight out of the box.
Pros
- Inexpensive
- Lightweight
- Has the alarm that sounds if rates are too low
- Nice design
Cons
- Not sturdy enough
- Not suitable for smaller children
