Product description CONTEC CMS50NA Fingertip Pulse Oximeter The CMS50NA Fingertip Pulse Oximeter is the TFT oxygen monitor that can measure SpO2 value up to 100%. The PR Display Range: 30bpm~250 bpm Resolution:1%for SpO2 and 1 bpm for Pulse Rate. The pulse oximeter is ideal for use at home, exercising or on the go. Warning:Pulse oximeters give an estimated oxygen saturation level value. Several research studies and an FDA 2021 safety communication have found that certain physical traits, including but not limited to darker skin pigmentation and melanin, may make the oxygen level estimated value appear higher than it actually is.Users are strongly recommended to establish a baseline value when healthy and at rest. It is recommended that users consult a licensed healthcare provider or professional on how to interpret user readings based on physical traits or characteristics. Accurate SpO2 Levels Contec pulse oximeter accurately determines your SpO2 (blood oxygen saturation levels) in seconds. SpO2 measured value up to 100% Reliable Heart Rate Real-time heart rate and PR Value Waveform at home, athletic and aviation use. Multi Directional Display The monitor offering rotatable display in 4 different layout options for your convenient reading. Adjustable TFT Display 5 levels of brightness to choose from to adapt to reading in different light. Hypoallergenic The fingertip clip is soft and easy to apply, hypoallergenic free. Easy Battery Installation The quick-snap-on battery cover allows you to place and remove the battery with complete ease. The 2 batteries are still required to be installed in opposite polarity. Infrared Sensor The CMS50NA monitor will give accurate reading and auto off when no signal in your daily use. Small & Portable The light-weight oxygen monitor is about 50g(with the batteries). The demision of CMS50N is 2.36 inches (L)*1.3 inches (W)*1.34 inches (H) CONTEC CMS50NA Display Type: TFT SpO2 Measured Range: 0%-100% SpO2 Accuracy: +/-2% SpO2 Resolution: 1% PR Display Range: 30-250bpm PR Accuracy: +/-2bpm PR Resolution: 1bpm What's in the box?

Review: Accurate, easy to read, works phenomenally well - This was easy to use, and very accurate when comparing to my Drs pulse oximeter. You do NEED warm hands or the pulse oxygen will be off, but this is standard with these devices. It comes with a carrying case and batteries! Excellent value and functionality. Review: Great little device to add to home first aid kit - I purchased this at the recommendation of my wife so we could add it to our first aid kit. She is a nurse treating COVID-19 patients, so she is concerned that she could be exposed to the virus at some point. She wanted this because one of the earlier signs of being positive for COVID-19 is apparently having low SpO2 so this is simply a tool to help her check herself or me for possible early signs of the virus. She was quite happy with the little sensor, as the display auto-rotates depending on how you are holding it. This simply means you won't be having to try and read it upside-down if you have it on one hand opposed to the other. Another thing she was quite impressed with is that the display also shows the waveform of the pulse. According to her, this is useful as it can show if it is getting a good reading or not. Because the display is so small, the waveform isn't all that precise, but it is good enough for her to use it to improve readings. Also it is worth noting that while this obviously works on both my and my wife's fingers, we found it also works on our children's fingers (age 2 and 4). I have seen pulse-ox sensors specifically for children and while that might be more necessary for someone using it more often, this larger sensor works just fine for their smaller fingers, as long as they hold still and have their hand/finger resting on a table for stability. Results for them also look accurate so that was a very nice surprise. In these crazy times it seems having one of these in your first aid kit might be a good idea and the fact that they are inexpensive makes it a no-brainer.

Accurate, Fast, and Easy to Read
This little pulse oximeter has quickly become an essential tool in my home. It gives fast and accurate readings of both oxygen saturation and heart rate within seconds of placing it on your finger. The bright display is clear and easy to read, even in low light. I tested it multiple times and found it consistent, matching readings from more expensive medical units. The build feels solid, and it is lightweight enough to keep in a pocket or gym bag. I use it regularly after workouts and when feeling under the weather, and it provides peace of mind. Battery installation is straightforward, and the auto shut-off helps preserve power. While it is not a substitute for professional medical advice, it is a great home health tool for anyone who wants to track oxygen levels quickly and easily. My wife has a tendency to pass out, which is why we got it! I also included a short video demonstration so others can see just how fast it works.

Literal life saver
I bought this during covid, and haven't had a real use for it until today. This thing probably saved my husbands life. He passed out and was acting out of breath and confused. His bp was lower than usual, he developed a chest rattle, and his oxygen sat was 71%. Emergency took him to the hospital with a suspected blood clot in his lung, most likely due to a sports injury in his ankle. Without seeing his oxygen saturation we probably wouldn't have known this was an emergency.

Very accurate and easy to use.
I compared it to my doctor's pulse oximeter and it was very accurate. I love that it actually shows your heartbeat line instead of just the beats per minute. The screen turns depending on the angle of your hand, so no matter which way it is, you can read it. The screen is a good size to be able to see all the information easily. It is comfortable to wear.
