  • Two meters failed out of the box By on 4/10/2017

    I ordered RODI system with this meter- out of the box and a second meter failed to register.
  • Ok By on 1/14/2017

    Works ok, but need to be careful to avoid damage. Seems to be accuarate.
  • A must By on 3/16/2016

    The unit is simple, accurate, easy to install and a must for your RODI system. I'm thinking about adding another Deionizer and wish I had bought the triple unit for a few dollars more, but still an excellent buy.
  • Don't waste money on replacement filters By on 3/9/2016

    Basically this will allow you to take the guessing game out of when to replace your RODI filters. This is super easy to install and easy to use. To be fair I have no way to tell if this is accurate since I am completely relying on the TDS meter on this unit. But I did use this right after I changed all my RODI filters and I had a TDS of 320 going in and a TDS of 1 coming out. I use a 4 stage/75gpd RODI unit.
  • Easy to install By on 2/5/2016

    No more guessing when it's time to change filters, resin or membrane.
    Always trusted a local shop with a stick meter, that was a mistake I'll never make again. This meter is accurate and easy to install. Great price too. Wish I had ordered this a long time ago.
  • Accurate Reading! By on 1/13/2016

    This is the most accurate meter I have owned!
  • Can't go without By on 12/21/2015

    Works as advertised. Good to know when you're producing quality water!
  • Worth every penny By on 10/21/2015

    Its too good of a price to pass on if you dont have something to read tds. Highly recommend it. Works like a charm
  • Great Product By on 7/19/2015

    This works as advertised. Does exactly what I need it to do. Purchased this back in Dec 2014, and its still working perfectly.
  • Very Nice Product By on 6/28/2015

    Works well, I haven't had an issue with it yet, I have the 1 in and 1 out, I disconnected the out due to misplacement of the inlet valve not in line with my unit, I had a small leak, as long as the out is working I am good.
