## Description

Newentor CO2 monitor is committed to escorting the activity environment of our life, study and production. CO2 detection is an easily overlooked but essential factor for us. Especially in crowded places and long-term closed spaces, it is easy to cause breathing difficulties. In dry seasons that are prone to fire and winters when doors and windows need to be closed, we need to pay more attention to the concentration of indoor carbon dioxide in real time.

Review: nicer than expected! The picture doesn't do it justice... the display is actually very vivid and pleasing esthetically - which isn't evident from the product's photos. Also note mentioned (perhaps I missed it?) that you can lightly "touch" the upper part (there's sensor there.. not a bottom rather sensor - just gently place your finger there) that toggles between 3 illumination modes - bright, med, and display off. (useful for night time..) Sensitivity wise - seems very accurate, consistant and fast (when on AC power, updates every few seconds). Didn't need to calibrate it as well. It seems accurate out of the box. In the morning when I open all windows wide open, it drops very rapidly to ~400-ish... Seems genuinely responsive to the environment. At night time, without ventilation, it showed around 1500 which is not good. I started ventilation, it dropped to ~800 during the night. You can really get a sense that it's reflecting the actual situation. I can tell the difference when 2 people are sleeping the bedroom vs. one. In short, very nice. Would have been even better if it had WIFI !!! and connected to home assistant. over-all very very nice and useful. Helped me solve my C02 problem. (at first I wasn't ventilating enough, I ramped up the RPM on the inline fan, and it dropped to 800, which is OK, during nighttime).
Review: product did not fullfil my requierment.may be my mistake also select worng item.

Most of what you're paying for here is the CO2 meter, and even if that were all this did, it would be good value versus other CO2 meters I've seen on Amazon. It has a big clear display, it can track a high-low range over time, and it can sound an alarm above a customizable level. Dual options for battery and DC power are also welcome. A perk of the battery option is that you'd want to take this outside to recalibrate the CO2 meter (since calibration is based on outdoor levels of CO2). Is it accurate? I don't have more expensive equipment to measure properly, but I do have other consumer-grade meters for temp, humidity and CO2, and this gives very similar measurements. The CO2 measurement is within 50ppm of another meter from a different manufacturer, with the out of the box calibration. It also reacts like you'd expect it to, to things like having more people in the room, or exhaling in its direction. So I have confidence that it isn't just making up numbers, it is actually measuring CO2 levels, and is decently accurate for basic monitoring purposes. As you can tell, I already have a CO2 meter, but what I like here is combining that with temperature, humidity, time, and date readouts, all of which are also useful to have at a glance. I might prefer the clock was more prominently featured on the display, rather than the CO2 measurement (which isn't that dynamic, you either have good ventilation or you don't), but it's all bright, crisp and easily readable.
