CO2 Controller, 0-5000PPM Carbon Dioxide Controller with Human/Plant Mode, 15ft NDIR Probe, LCD Trend Display, Audible Alarm, Day&Night Relay, CO2 Monitor for Greenhouse, Grow Rooms

This thing works the best out of all of the CO2 controllers. Don’t waste your time buying any other one I did and it was a waste. It’s very accurate and easy to use I highly recommend.

I am pleased with this controller. I own a mushroom growing operation and recently gave this controller a shot because my old one finally kicked the bucket. I like the options and easy readout of this one. It was easy to program and calibrate. It took about 20min to setup all my preferences and then it was back to work. I have had it several months now and I recalibrated last week once and it had only swayed 18ppm that is good enough for government work as they say. The price was on point and I will be buying two more for our next expansion.

This controller works like a charm. Absolutely accurate and it couldn't be easier to set up. Numbers are large so you can see them and the co2 remote detector has a green light so it doesn't disturb light cycle of plants. $100 less than the leading brand and works just as well!

This works fantastic so far , it’s very accurate, if I put it with pulse it’s all but identical, on opposite sides of tent it is about 80 ppm off but it’s the distance from the co2 emitter . Otherwise it’s right on .

The controller is not very intuitive or helpful from a user interface or a data standpoint. I used it in a mushroom fruiting chamber for 5 months and it was great. I took everything apart to make a new one and when I plugged it back in a week later it’s getting intermittent power for some reason. I didn’t drop it or have any other changes to the device that would cause a malfunction. I took the case apart to check the connections and everything is secure like it should be. Fuse is good. No idea what else to do since everything is in the motherboard. Do I have to buy a new one? I’m stuck without it. Very frustrating.

This product works as stated. A good basic controller.

Needs to be recalibrate before you use it. Works pretty good for the price.

I just wrote a review on the controller I had before this one and theirs was 2 stars. This controller is great! I love it! The value is excellent, the air quality stay in line with exactly what I need it to be and the installation was a walk in the park including set up. I was worried about getting my co2 levels adjusted but I had no issues getting it going.

Muy fácil de utilizar

El producto cumple su función venía en su caja lo que no me gustó es que venía solo en una caja sin protección alguna contra golpes en el manejo de la paquetería

Works great. Still going strong 2 years later
