Deb, no not just for field testing at all. In my line of work, alot of the laboratory testing is done via burette titration. The digital titrator is good because it is as portable as any other testing equip....and I believe it is accurate enough to give you the results you need. As an I example of what meant by reagent strength: if hardness or alkalinity are expected to be >100-200ppm, I use a reagent where the multiplier is 4.0....if the hardness or alkalinity is expected to be <100 ppm, I use a reagent where the multiplier is .40 . Like I said, it allows me to more accurate on lower levels & fast/accurate on high levels. Once you get the hang of it, maybe a minute per test...so its fast. On the ammonia, I cant help you there. I make my living with water, but it has nothing to do with ponds. It's heating & cooling water. You guys spend all your time trying to get stuff to live in your water...I spend all mine trying to kill every thing in my water!
It ain't much of story if you don't have pictures!
