Imo,dont even waste your money on the strips.I did and its a joke.I have the oakton PH and PPM,with replacement electrode paid about 150 usd for both.Im not gonna ever usem agin as im back to soil.You need to calibrate often i did every week.PH is very important in hydro you can lock out certain nutes causing deffiencies lol early dont know if i spelled it right.Good luck with the grow.I dont know if a temp gage for your solution was in the list But i advise you get 1.
