Alkalinity PPM Colorimeter HI755 Hanna Checker - Marine Water
The Hanna Alkalinity checker is an awesome little tool that will give you accurate easy to read results. If you have bad eyes or have a hard time with titration test kits, the digital read out on the Hanna checkers is super nice and easy to read. The biggest key with Hanna checkers is keeping the vials nice and clean for consistent results. The Hanna Alkalinity Checker does give readings in Parts per Million, which can easily be converted to DKH or meq/L.
Three simple steps to results. The Hanna Alkalinity Checker bridges the gap between simple chemical test kits and professional instrumentation. Accurate, affordable and easy to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Hanna Alkalinity Checker, press the button and read the results. Done.

That would be the correct reagents, it is actually doing the same test, just displaying the results differently.
Still reads much lower than Salfert.
Even with the 5ppm error range in the Hanna. I can not make heads or tails on this.
I am sorry to hear about the differences in your test kit. We have had great luck with hanna in the past and certainly have used their products and standards regularly. At this point we recommend reaching out to hanna to ensure the checker is up to par and functioning correctly with the use of standards or other re-calibrating effects.
