As far as I know, and I have checked, no. There is no way to calibrate a Hanna checker or master checker yourself. Here is the number for Hanna: (401) 450-6051 They will help you to set up a servicing for your devices.
Well, you can only test one at a time, the amount of time takes the exact same. For me that is not a reason enough to get the other ones. However, if you only want to test a few of the parameters, then the other ones make more sense because you can spend less money to get them. I do recommend this because I really do it and the convenience of having it all together. It is personal preference and I’m good either way.
My point is, if you have the individual tests, you don't need to wait for one test to complete before you can start the next. We don't all have a spare day each week to test. Testing needs to be quick and easy
I see your point. I think the individual testers would be better as when it comes to Hanna I only use it for No3 Po4. No need to spend north of $450 for 2 tests.
Is there any way you can calibrate this equipment if you’ve bought it secondhand?

well hopefully yours turns on. Mine doesnt. Just shows the Hanna logo then turns off. Been trying to contact Hanna for a week now with no luck.
Dang man. I am sorry to hear that. Have you reached out to Hanna? Mine has worked like a champ
Better off buying the testers individually. Takes way to long to do the tests on that unit
