shaywood Posted April 6, 2018 Share Posted April 6, 2018 I own a Hanna HI755 Alkalinity tester. I ordered a replacement reagent and ordered reagent for the HI772. Does anyone know if they are interchangeable? Shawn Quote Link to comment Share on other sites More sharing options...
Exodus Posted April 6, 2018 Share Posted April 6, 2018 If you have a Blue Hanna Checker For "Alkalinity" That Says "Marine" on the Lid and your Intentions are to Test Saltwater, then the Reagent Bottle you are using should say "HI772S" If it says anything else, you have the wrong reagent.

shaywood Posted April 6, 2018 Author Share Posted April 6, 2018 Found this on Amazon. "This reagent works with both the 755 & 772 Hanna checker. It may come with the tag 755-26 or 772-26, both reagents work with both checkers. " Quote Link to comment Share on other sites More sharing options...

" I would personally send the question to Hanna and see what they say but I personally wouldn't trust an individual sellers advice on Amazon, BRS Sells them at only $8 a bottle Quote Link to comment Share on other sites More sharing options...
Oregonic Posted April 6, 2018 Share Posted April 6, 2018 According to BRS it works for both checkers. https://www.bulkreefsupply.com/hi772-26-alkalinity-checker-reagents-hanna.html 1 Quote Link to comment Share on other sites More sharing options...
Willapa Posted April 6, 2018 Share Posted April 6, 2018 Same thing happened to me, thought I ordered the wrong stuff but apparently interchangeable. It's been working just fine.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
