CONTEC CMS50NA Pulse Oximeter Fingertip Blood Oxygen Saturation Monitor SpO2 and PR Value Waveform Blood Oxygen Neck/Wrist Corda, Grey

works great

Here is my opinion as a real user. Having Asthma I like to keep up with my SpO2. I have this model and a ten year old Contec model that appears the same. Have taken both to my Doctor visits and found they agree almost all the time or off by one point at worst. Very easy to use. Relatively compact compared to some models. I am most impressed at the durability of the prior similar model and the very low cost for such an accurate device. Highly recommend it.

Easy to use and accurate

I love this monitor. I use it everyday. The quality is great

Works as expected. It does take it a little longer to read o2 saturation level than most sensors

Hasta ahora no he tenido problemas con el oximetro

I purchased this pulse ox because I am a nurse in a clinic. It works very well and I love the layout of the readings. The numbers are large enough to see too. It’s built well and very reliable. My patients are always surprised when I tell them what I paid for it. Would highly recommend!

Works great for the price! My whole class uses this and we love how easy it is and how long the battery lasts.
