Air quality is very important in our senior center and this monitor delivered more than we expected.

It has been so nice to monitor our cO2 levels, especially during these winter months where we aren’t allowing as much fresh air in! Great purchase.

Really like this thing. I have it in my sons room so I can monitor temps and humidity. Easy to setup and calibrate. Just take it outside and hold the three buttons on top to calibrate. Unit came in with dead batteries so i had to charge it but battery life seems to be pretty good. Numbers large and easy to read

CO2 turns into Carbonic Acid (H2CO3) , which lowers your PH. This tool can help monitor your household CO2 Level, so you can know when to open a window temporarily or to know if you should be using calcium hydroxide media(CO2 scrubbing media) to help maintain a high PH.

I don't know if this thing is scientifically accurate or not, but it does measure what it says it measures.
The CO2 read high 500s to low 600s indoors. Particulates 002 to 005. I took the device into the kitchen, closed the door, put it near the gas stove, and put the kettle on. CO2 climbed to over 1500 by the time the water boiled. Particulates stayed low.
Then took it into the bathroom, closed the door, and struck a match. Particulates went over 100 in less than a minute and the alarm went off. CO2 stayed in the 500s. Turned on the exhaust fan, particulates came back down to 002, CO2 into the high 400s.
Temperature reads a couple degrees high, probably because the device generates a bit of warmth. It comes with a charger and cord.

I originally purchased this unit to monitor C02’s effects on the pH of my fish tank, but have also appreciated just knowing how the air quality is in the house. The thermostat and humidity are another bonus.

When I had it set up in my bedroom and my dogs came in the room the co2 levels would quickly rise. I've got it in my tent now and it's working great.
