Just looking for some feedback from people that use oximeters on a regular basis.
The one we use at work is pretty reliable, but occasionally won't get a reading from someone. I've heard from some folks that this can happen if there is too much dirt on their fingers, or if it's cold out, or the person's fingers are too cold. Can anyone confirm if this is accurate?
I'm also curious if anyone has experience using different brands. Is there any difference between them? I know most are rated to a 2% variance, there doesn't seem to be an obvious difference between the brands other than aesthetics. Looking to pick up a few more, any feedback would be appreciated.
