Alkalinity Colorimeter HI755 Hanna Checker HC - Marine Water

SKU: 206201


  • Works Like a Charm By ncoble4 on 12/15/2014

    This test kit is easy to use and works as advertised. The only reason it does not get 5 stars is that the bottle of reagent does not seal properly after it is opened for the first time. I found this out the hard way by screwing the cap back on, placing the bottle back in the plastic box and putting it on the shelf. The next day when I went to test, the reagent had all leaked out in the box so I had to order more. :(

    Now I keep the reagent upright on the shelf separate from the box.
  • Easy Alkalinity - works great By Jon S on 12/15/2014

    I have the Hanna Phosphate meter and recently purchased the alkalinity meter. This is so simple to use, and I like the numeric readout. Well made and takes the guess-work out of water testing. Now if they would just make one for Nitrate.
  • Makes reefing life simpler!!! By Darren on 12/15/2014

    I bought this along with the Calcium and Phosphate checker. No more wasting time guessing, these gadgets makes it fast, easy and accurate when getting your tank parameters in order.

    I have used the alkalinity tester and it is really easy to use and read. I would recommend this item to anyone.
  • Testing made easy By Jawstone on 12/14/2014

    Product gives a very accurate reading and is easy to use.
  • Quick and Easy - Highly Recommended By Davide on 12/9/2014

    This testing kit came to me highly recommended. I'm glad I bought one at a very competitive price as a BRS doorbuster. The testing process is quick and very easy and seemingly accurate. My only complaint is that Hanna doesn't give you very much testing solution. My advice is to buy an extra one up front when you purchase this unit.
  • Like this unit to date. By PingZing on 12/9/2014

    Just beginning to use. First test read very close to a standard sample. If trying to test for a specific level just convert ppm and either you are aboce or below. My third Checker.aa
  • Great Product By Jeff on 12/9/2014

    This product is easy to use and provides very clear results. I use in conjunction with Red Sea Alk test and the results were always accurate.
  • Liking this tester a lot so far By Jeff on 12/9/2014

    Got this to use as a backup to the Red Sea titration test and this will probably be my primary tester going forward, I like it that much. The only way they could have made it even better would be to include a sample card giving common dKh for a given ppm reading. As it is, you just take a calculator and convert the ppm reading to its equivalent dKh reading. Seems very precise and I can see why these are so popular with reefers
  • Now i'll actually test my alk By Ryan on 12/9/2014

    It's not that my red sea test was all that much harder but this takes all the guess work out. fill with 10ML, add the reagent (liquid!) and press a button. that's it, no reading colors and thinking is that blue enough or is that more purple? best part is it's repeatable, I took a cup of water, filled 2 of the glass things with 10ML each and got the exact same result.

    if you're lazy like me, this is a test you will actually use.
