CO2 Controller, Briidea Day and Night Programmable CO2 Controller and Monitor for Greenhouses, Remote CO2 Sensor

Perfect

Don't waste your time or money. Accuracy is terrible, it's lags so bad, and it's useles, your better off not using the controller and just doing the math or guessing the flow rate to set the regulator at. It is not operator error, it's a cheap useless POS. The only reason I didn't return it is because I didn't use it when I first got it. I spent countless hours testing it in numerous different setups/configs, literally days worth of man hours. It's so bad it boarders on criminal, after this experience I wouldn't buy a washer for a c02 Regulator from this company. A cheap useless Chinese product, obviously no R&D or testing was done, they must just hope that you don't realize you got robbed until the return period is up. I would be ashamed to sell this product to someone even if I was trying to rip them off! STAY AWAY!!!

So this thing works really well it's good I like it a couple of things I think would have made it over the top and even better and I would have given it a five star would have been a backlight it stays on so you can see it and a little better instructions you know just you're kind of learning on your own.

This product does exactly what is supposed to do. Programming isn't to hard. But dont loose the directions for this one. Cant find a pdf manual. Other than that, she's a boss.

We like everything about it, it was perfect for what we needed to use in our grow house.

Program is difficult to set. Not user friendly.

Nice controller for the money

I wouldnt reccomend buying this unit. It reads about 900ppm low. I have calibrated and recalibrated it. It will read outside air corrctly but does not read high concetration very well. Its has a very slow refresh rate on the sensor and will drain your co2 tank in about two days. I have checked the ppm with two other co2 meters which both were reading 2500ppm when i had it set for 1500. I tried manually calibrating the sensor but it only lets you adjust by 150 ppm. If you wanna kill yourself or some plants get this unit otherwise i would stay as far away from this thing as you can
