So, I finally broke down and bought some Hanna Checkers, I've been in and out of the hobby since the late 80s and have always relied on titration tests but with my latest system I have not been able to nail down my parameters, I tested one number and my LFS with my own test kit tested a wildly different number. I know these test kits vary wildly from manufacturer to manufacturer and from user to user but my own back to back tests were all over the place. I know Hanna tests have variations but for me and my old ass eyes it's much easier to read a digital number display than try to distinguish between shades of pink, blue and green.
Just wanted to share this to save you guys some money, these are the same exact replacement cuvettes for your Hanna checkers only difference is they don’t come with caps but you can use the ones that come with the old cuvettes, just remember to save them! Copy this link 👇🏽
