Using it to monitor air quality in closed spaces such as bedrooms, restaurants, malls.

This meter is not the cheapest but it seems to be worth the price. Having the meter in a prominent place encourages us to open the windows to get some fresh air.

Overall does it’s states job with a nice display. Easy to place anywhere in house. One improvement could be optional replaceable batteries (vs charging only, as it needs to be charged fairly often).
Alex –
Very sensitive.

The device comes nicely packed that included long cord so you can keep the device charged while you use it. The device itself is small so it won’t take up a bunch of space. The device reads the co2 level, temperature, and humidity also has a alarm that alert ‼️

I’ve only had this product for a few days, but it seems to be working nicely so far. My goal is to evaluate the impact of my whole-house ventilation system on CO2 levels in the home. I appreciate that it can be either plugged in to run continuously or operate on batteries for up to 10 hours. It appears to be accurate; for example, I left it outside for 10 minutes in a well-ventilated shady area, and it read 424 ppm, which matches NOAA worldwide data. Indoors, it ranges between 600 and 900 parts per million. Every few seconds, the display is refreshed. I haven’t tried the 7-day history download feature yet, but it’s something I’m interested in.

Nice size, nice colorful readout. Battery as a back up works fine
