  • Accurate Reading! By Tony on 1/13/2016

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

    Works as advertised. Good to know when you're producing quality water!
  • Worth every penny By Corey 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 Randy 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 Eagle1 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.
  • Works perfectly By Craig on 6/26/2015

    Works perfectly, letting me know my TDS before and after my DI resin. I bypass the DI resin until my TDS is below 10 and then monitor both sides after that. Recommended.
  • Nice Unit By Eagle1 on 6/11/2015

    Installed this dual meter on my RO/DI unit today, I had to make up some different connections to get back to the supplied "T" on the in side but wasn't too much of a hassle, meter is correct on what my water is 120 going in and 0 coming out.
  • Easy and Efficient By Ed on 5/29/2015

    Took about 5 minutes to set up, easy install, easy to use. Everyone should have one!
  • I don't know why I didn't order this sooner! By Butch on 5/29/2015

    This product is easy to install and even easier to use. If you are in the market for an RODI, purchase this at the same time to take the guess work out of what your TDS is on each and every water change.
  • Does the job By phil on 4/4/2015

    I bought this already installed on 4 unit RO/DI system. First one stopped working after about 8 months. could not check if was batteries as was unable to find any batteries that I could replace. Fortunately after contacting customer support found out that it was still under warranty and they immediately sent out a replacement. Happy once again and kudos to customer support. The meter is a nice thing to have on my RO system.
