Review on 🌑️ Accurate 99% Precise Humidity Temperature Detector: Ideal for Optimal Conditions by Nick Narvasa

Perfect at a Glance CO2 Temperature & Humidity Gauge

I need a CO2 monitor for my office because sometimes I get a headache or afternoon drowsiness and I wanted to see if CO2 is to blame. There are several on Revain and I chose this one for a number of reasons. It can display temperature in Fahrenheit, not just Celsius, it displays humidity and then of course CO2. The fact that it runs on 18650 is just a bonus because if the battery (which is included but not documented) dies you can easily replace it. Some of the others for sale have built in batteries and will just stop working when they die. I don't have a commercial CO2 meter so I can't say how accurate it is. I could rent one if I feel wrong, but I'll just make a statement with the idea that there's a small fabrication factor. It says +-50-5ppm so it should be pretty accurate. You can set a high CO2 alarm. You can switch off the sound signal. This is very important as some electronic devices emit a very loud beeping sound that you cannot turn off. It includes the longest USB-C cable I've ever seen, so getting power from a distant outlet isn't a problem. And bonus: yes, it's USB C, not micro. The instructions are a bit sparse, but I was able to quickly switch from C to F, turn off the beep, and program whatever I needed, so no problem. A wall mount is included but I will only be using it on my desk. The image also shows a magic wand to give you an idea of the scale. It's a really great device, all things considered. Sets all checkboxes to what I wanted. It's not a clock, it's CO2, temperature and humidity. Easy to read, you can adjust the brightness for auto or manual brightness control. I've tried to find something to bring it down from five stars but haven't found anything wrong with it. You've come to the right place if you're looking for a CO2 monitor.

Pros
