The hanna checkers id recommend are the All, Phosphate ULR and Nitrate HR. The Nitrate LR, Calcium and others are either not accurate enough or too difficult to use.

Is the alk the one i need or correct?

I can't believe I'm posting this on another thread but, just watch out for the Nitrate HR as you currently can't buy the reagents.
HI701 is free chlorine and not Alk; I use HI772 for Alk.

Is the test accurate

Which one?
My Alk tests were a little variable, but I've found it better than the Salifert I am using to double check it. I also found it's a lot better if you don't clean the syringe between uses. There have also been reports that the reagent varies from bottle to bottle but I still think it's ok.
Nitrate HR seemed good for the 10 tests I got out of it before I ran out of reagent. Now I am back to using NYOS. :mad:

NYOS is an aquarium product brand and they make test kits (amongst other things).
I haven't been around very long but I use:
Hanna for Alk and ULR Phosphate
NYOS for Nitrate (and maybe return to Hanna in the future if I can ever get the reagents)
Red Sea Calcium Pro
Aquaforest Mg (which isn't my favourite but, apparently, is one of the better ones)

So they're pretty accurate

I recently got the HI772 for alkalinity and I tested my water with it, my red sea pro test and checked it against my trident and they were all within a margin of testing error.
It and one of the low range phosphate checkers are the necessary checkers in my mind. The HR nitrate is nice but I've only used it a few times because of the current lack of reagents.
The copper is also valuable if you treat fish with copper.

Yes, remember though, it’s consistency you are after and not necessarily accuracy, if you use the same test kit and it consistently give a slightly high or low reading but it does that with every test, that’s better than a test kit that is accurate but hard to read or hard to carry out the test correctly to get that accurate result.
Out of all of the checkers I would say the PO4 checker is a must buy, the alk and the nitrate are good to get if you have the spare money, as both of those have cheaper options that are good ,such as Salifert.
Nitrate lvls don’t need to be that precise and other test kits for alk give as accurate results as the checker.
po4 stands for phosphate, I have this one in the below link, I find it excellent. Hanna do a couple different ones but the two main ones are the 736 model or the 774, the basic difference is the 736 gives the reading in phosphorus and needs converting to phosphate, the 774 does the converting for you, Hanna have said previously both have the same accuracy as soon people claim the 736 is more accurate.

The HI774 Ultra Low Range Phosphate Checker® is a cost-effective way to measure phosphate in marine systems, including reef tanks. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp...
