    Testing your alkalinity has never been easier. You can get an accurate reading in less than a minute. This product also gives you a consistent reading, just make sure your reagent has not expired.

  • Easy to use By Charles on 4/26/2014

    I have been using the Hanna checker for 3 months now. I don't think I could ever go back to any other type of test kits. I love the repeat illite of the test results.

    Easy to use, love it
  • Awesome, Easy and Accurate...Consistent By JPB on 2/13/2014

    Easy to use and very consistent results. For the first few months I double checked occasionally with a Salifert titration test...results very similar. Titration can be challenging to determine exact endpoint, especially if you rush it...not at issue with this test. :)
  • Works great By Mtthbrook on 2/9/2014

    Product works great , beats color charts
  • Good product By John on 2/1/2014

    I am new to the hobby and found this checker very easy to use. None of my criticisms of the phosphate checker apply here - no problems with timeouts or reagent packets. The results are easy to read.
