Which Hanna pH Checker is better???

Hey! I want to buy a Hanna pH checker, but I noticed there 5 different types. Which one is better and/or more accurate? Thank you!

I've been eyeing the HI780. Following along.

I’m also wondering about the HI780. Hopefully there are some people with experience with these.

I am guessing not many have not been in the market to purchasing one. Probably already had ph probes and the like already in use on their systems. I'll probably just end up buying the HI780 when the budget allows. I'll provide a follow up when that happens.

I have the 98108, I like it, no water sampling and reagent. Just hold in the tank for a moment and read the value

How often do you calibrate?

I have the Hi780 bought it a few weeks back seems accurate (bought certified calibration standard with it). Very easy to use put sample in add 5 drops of reagent put it back in and done.
