I bought one, mainly for PAR measurements. I used the slide and followed the directions on installing it. It was off about 1 degree on temp and the pH was off a little also from my other meter, but not horribly.
I thought about testing it for a few more months, but I have mixed feelings about it. I have sponge growth and spirorbid worms in my sump and would hate for it to get fowled up by them. I need it as a PAR meter more.
