i bought a blue lab that does temp and ph,personally i dont like it,first off the cap is a bitch cause it fits so damn tight,but the realproblem is its accuracy,il callibrate it in 7 and then 4 and then fresh water rinse inbetween and then fresh water rinse after,then back to the 7 solution and it will read 6.7 not seven and fresh water rinse and into 4 solution and its up around 4.4 im not happy with mine and am actually taking it back tomorrow,this is just my experience....
I will agree to disagree. My blue lab is not new have had it for awhile now..
My blue lab is not a toy... IMO PH is a must know in hydro... [snip]
pH is a must know but, pens and meters are in no way required. [snip]
I will agree to disagree. [snip]

The amount spent on a pen/meter should be determined in the same way as a loan to a friend. Never put out more cash than you're willing to throw in the trash
