Hydro Innovations Hydrogen CO2 Monitor

Works great. Controls the C02 generator perfect.

Bought this with the HydoGen Pro CO2 Generator. It does it's job perfectly. Have used it in 2 grow cycles and it is great. No fuss, no muss - it just works and keeps everything perfectly regulated.The company is amazing as well. And their service is unparalleled.If you are looking for a C02 generator and brain/monitor - this combo is off the charts.Buy it.

Looks like a good unit considering the price seems to work well would have given a 5 star but shipping was very very slow it did arrive by the latest day posted but for the size of the item I had expected it to take a week tops not close to 3

Well Built. Does every thing it was made to do. good job ! Matchs up great when used with HydroGen CO2 generator.

My son needed to test CO2 levels in the air for his science fair experiment. We searched everywhere looking for an affordable way to do it. We found this product and it worked awesome. Delievery was prompt and it worked just like it said in the directions.
