Yea, cause i dont wanna kill my plants cause i was too cheap to spend $30, considering all the money i have already spent... I just always seen them for $2-3 hundred dollar but $30 to $50 isnt bad at all...

You can use any kind.The more you pay the longer they last. I paid like $5 for my truncheon wand (tds,cf and ec meter) and I paid about $24 for my ph pen.As long as the ph pen is calibratable and the ppm meter will go to 9999 it will work
