Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We have a selection of different items received in this mailbag, I’m gonna start with this little guy, it’s a pulse oximeter. The model number, at least on the packaging, is YK-82C with a pretty recent date code as well, September 2020. So I got this pulse oximeter to keep around cause during these times, I think it’s a good idea to have such a device to monitor the level of oxygen in your blood, you know just in case you have an unfortunate event with well you know what, let’s not name it. I think this particular model is pretty nice, they also include an EVA carry case. It doesn’t come loaded with batteries but it uses 2 x AAA batteries which is nice. Single press to turn it on, it will auto power-off if there is no finger present for taking measurements, that’s pretty nice. Short press of the switch will cycle through a few different display modes in a couple of orientations, as we can see it uses one of those popular two color OLED displays.
