Thats true.But it'll still let you (know) that somethings not right so you'll know to start looking.
ok, can you explain how its gonna let me know? i didnt think that it had any kind of indicators on it, i thought it was just a non coroding probe that you stuck in the water, and then the wire could carry off anything that was in the water(electricity wise)
not being a smart-a$$, but how will it let me know anything?
