I am a reefer and bought this to monitor indoor co2 as that affect the ph of my tanks. InkBird brand have the best temperature controller in the hobby, so I do not hesitate to get this from them. The screen is bright and clear, with a scale gauge, it is easy to spot the level from across the room. Ever since I received this, I also use to monitor and compare co2 level at different locations at different times of the day.
Now I know the level of my bedrooms as well.
Trying to know when I should open up the windows to circulate fresh air inside!
I should have gotten this earlier. Not this double duties for my hobby and also health related reasons….. so this should be able to substantiate the purchase with my dear wife…😉
