Electrokate Posted September 19, 2011 Share Posted September 19, 2011 Getting really weird test kit results and hoping to find someone in the Portland area with a good colorimeter to check my results against. Can anyone help me out? Test kits I have access to are LaMotte vs API. Link to comment Share on other sites More sharing options...
Smann Posted September 19, 2011 Share Posted September 19, 2011 I have a hanna checker, the laMotte seems pretty good , sometimes a little low. I'm in West Linn, just off 205 if you dont find anyone closer, also have Macherey-Nagel test kits to check against Link to comment Share on other sites More sharing options...
