Great device

Totally thrilled with it

good seller

Great for science project

Worked great for our School science project, measuring and logging direct air capture of CO2 using an Arduino and laptop.

Great Meter

This meter not only shows the current co2 level but records the maximum and minimum readings for instant recall.

I am very pleased with this well built unit.

Remote CO2 Storage Safety Dual Alarm

The perfect monitor

This monitor controller is what I have been looking for for 25 years. It keeps the co2 levels at the correct levels. When they go to high the fan kicks on and runs until the co2 reaches 800 parts per million, which is the default setting. I just purchase 3 more one for each of my grow rooms. I feel they are very reasonable priced as well.

Worked GREAT!

We have continued to use CO2Meter CO2 Leak Detectors and they have worked great. It's nice not also having the headphones to deal with like other competitors. 5 stars!

Excellent Once Installed

The installation was difficult given the terrible instructions for a novice like me. Specifically, the wiring instructions assumed an understanding of thermostat wiring that required hours of Googling for me to comprehend. Now that it’s installed, I wonder why every new home doesn’t come with this standard to control the air exchanger. It is amazing to know that fresh air is drawn when needed, and not when it isn’t needed. This improves health and reduces energy loss. I was amazed to learn just how much CO2 I was allowing to build up in my house now that I can see the levels with this monitor. Now it is a joy to know my family has consistent fresh air (without running the exchanger into bankruptcy. :)

Better sleep

Kept sleeping like crap and waking up in the middle of night. Couldn't figure out why. Then I thought about co2 because I slept in a 10x10 room with the windows and door shut. Got this monitor and levels were 2500-3250ppm. Decided to start cracking door when I sleep with a 4" swing bar door lock. Now the levels never go above 2000ppm and are usually 1300-1900ppm. I sleep better now and rarely wake up in the middle of night. My advice is to crack windows as much as possible. Do it at night if you live in a hot climate. With nobody in the room that brings my level down from about 1200ppm to 700ppm. And always sleep with your door cracked at least 3"-4". The more the better. You can get a 4" swing bar door lock at Walmart for $5 if you need security.

Good for situational evaluation

I'm immunosuppressed, but with the "end of COVID" I will need to spend more time in rooms with multiple other people. CO2 is a good way of monitoring room ventilation, and I have been evaluating room safety based on the meter's readings. I have no way of evaluating the accuracy of the CO2 readings, but the humidity and temperature readings are spot on, so I feel the CO2 readings should be close enough for me to make a good estimate of a room's safety.

Very Accurate!

This device is working exactly as I expected. It's extremely accurate for being such a small device.

Worked fine and correct product!

Interesting tool to have when entertaining

It’s nice to be able to see when air quality is good or not. Knowing that we can open a windows or start a fan to circulate air helps folks feel safe.

We've been using the CO2 meter to take IAQ Measurements in buildings during Energy Star certification visits. It's been working well an updates quickly which helps us move around a building faster.

I just wanted to say our team is highly satisfied with the CO2 controller and we will hope to do future business with CO2Meter.

GREAT!

This product works excellently and CO2Meter always offers great technical support.

Open the windows

I am feeling better now I made our hose air tight. Put the power bill in the green. The CO2 in the red. Can’t win.
