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. "
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?

Tried using this in tandem with a Gyre 130 module. Didn't seem to work. For sale is the Gyre 150 IceCap Interface Module with cable (no Y Cable). $80.00. Pickup in Tualatin. Cash or PayPal.
