Hi, Chris: I have the synchrometer and all kinds of written and video instructions on how to get it to work, but I'm not smart enough. It gathers dust at my house. I'm looking to hire someone to do the synchrometer testing, but can't find anyone in my area. ACtually I can't even find anyone outside my area. I finally figured out that my house water is too toxic to fix (now that I've dropped $8,000 to change out the plumbing). So, if I live long enough, I'd like to be able to test the water in any new place I might buy. Katherine [(740)775-0148] or Katherinehine@hotmail.com
