I've been using a K-2006 by Taylor to test my water. I've seen apps and digital readers and I'm interested in a digital reader.
Anyone out there using some sort of digital reader to measure their chemicals?
I was looking at these:
eXact Micro 10 Photometer
6 in 1 Tester with ORP Electrode (http://www.amazon.com/dp/B00OXO992Y/...=IY5R876QHD0LN)
Any thoughts? Pros v Cons?
