So I did 3 Hanna checks. 8.2 8.2 8.2 and a Red Sea to confirm 8.2... The KHD is not correct but is giving a consistent number for 4 tests, so I use the % offset which doesn't seem to actually work properly so I have to just guess several %numbers until the offset finally reads 8.2... 8.2
Re-check with all three... 8.2 yay! Re-check again with KHD because I'm crazy and want to make absolutely sure... 8.2 YAY!!
So I set up some dosing overnight since 8.2 is lower than I'd like. I get up this morning:
3 Hanna checks: 8.6 8.6 8.6 and a Read Sea to confirm: 8.6
KH Director... 8.3... 8.4... sigh
I thought I had nailed it last night! I re-calibrated dosing pumps, I double checked the tube length. The only issue I was having was the % offset which was straight up wrong. (Unless the online percentage calculators have been lying to me for years.) But even that I managed to finesse and get the proper result test after test after test. Everything was on point. I don't know where to even start now... and yes, a .3 difference is a big deal. I want to be able to set-forget, not worry about it drifting, and simply confirm results with Hanna from time to time. If its already drifting within 12 hours....
