Measure your oxygen saturation and heart rate during the night

Are you looking for an oximeter for measuring your oxygen saturation (SpO2) for a longer period of time? During your sleep, for example? Try the CIRCUL Health Monitor Ring, a very comfortable and lightweight device. Put it on your finger, connect it to your smartphone with the free app and start measuring…

… When you wake up in the morning, you’ll have an overview of your saturation, heart rate and sleep stages in the app on your smartphone. The app will warn you in case of desaturation (oxygen deficiency). If this is the case, your therapy may not be effective (enough) and you’ll probably need to take action.¹ The CIRCUL Health Monitor has three internal sensors, thus ensuring accurate measurements. It measures no less than 100 times per second! Would you like to send your results to your mailbox? Share them with a healthcare professional? It’s all possible.

TIP: On the inside of the CIRCUL, you’ll find an arrow. The ring should be worn with the arrow up.

Optimal wearing comfort

The CIRCUL ring is available in three sizes: S, L and XL. The ring is quite flexible and adapts itself less or more to your finger size. Optimal wearing comfort guaranteed. At night, the ring cannot slip off your finger, which is often the case with a fingertip pulse oximeter. Depending on personal preference and fit, you can wear the ring on different fingers. In the table below you can easily read which size is appropriate.

International Award

CIRCUL has been very successful at the international level. In 2020, the ring was awarded with the Red Dot Best of the Best, a very prestigious design award. At the start of the COVID-19 pandemic, the ring was used in the fight against COVID-19 in Wuhan, China.

You can easily charge the CIRCUL on your computer, laptop or smartphone charger. Two USB chargers are included! Batteries are not needed. The CIRCUL is fully charged within 2 hours. The ring captures up to 12 hours of sleep data, and up to 18 hours of data during daytime physical activity.

Gaining insight in your sleep cycle

Measuring is one thing, monitoring is another. The product name already reveals its biggest advantage: the CIRCUL Monitor helps you to monitor important parameters. The app generates an overview with graphs and tables – on a daily basis! It also shows the different sleep stages in detail. How many hours a night do you sleep deeply? How many hours are you in REM sleep? How often do you wake up? With the CIRCUL, you’ll find the answer to these questions!

Also discover Exercise Mode and Daytime Mode

Sleep Mode is meant for measurements at night, while Exercise Mode and Daytime Mode are meant for daytime measurements. Exercise Mode will help you out during sports: it captures not only your heart rate, but it also the displays the calories you burn and it counts your steps. Daytime Mode is intended for daytime use as well, when you’re not doing physical activity. This mode captures your heart rate and oxygen saturation.
