Hanna LR nitrate checker

[NatsRams]

I have the LR checker that I really like and have been using for a few years. I’ve found that replacement reagent packs with reagents that haven’t expired are scarce, and was told by an online retailer that most people are going to the HR. That makes it sound like the LR will soon be obsolete.

Like I said, I like the LR checker. But I’ll have to move on. What tester would give similar performance? I prefer colorimetric testers like Hanna. Is the Hanna HR good at low concentrations (< 2 ppm)?

Hanna HR but to me, that’s a really low target.
Mine does 1.3 but in my case, Iam dosing that back to say 5ppm ish.

Even better is their UL Phosphorus checker.
The colour change is so slight, I can’t tell the difference.

CA and MG are crap, the sample size is too small to get a consistent read. Salifert does these well.

Hanna Alk is just easy,

Do yourself a favour and just move to the HR checker…sorry to be annoying and answer a question you haven’t asked but not sure of the benefit of targeting nitrate at such a low value.
The HR test is quicker and simpler to do too.

I use the HR and can't imagine needing to test any lower than 0.1

I wouldn’t worry about what an online vendor says. Buy your reagents directly from Hanna if you are tired of buying junk from vendors who are overstocked with low range reagents.

In the off chance the low range disappears, the phosphate Checker can read the color of other nitrate kits with the proper calibration and possibly better precision at the low range than the high range Checker. There are examples of this being done already, so fear not. There will at least be a DIY alternative.

Yes buy from Hanna, they told me they will continue producing the reagents.

Most folks are moving to HR as there is very little benefit and many disadvantages of operating a tank below around 2ppm, a level which can easily be read by the HR checker.

Having said that, there is no plan by Hanna Instruments to discontinue the LR checker and you simply need to find a Hanna dealer who will be able to obtain the reagents for you.

Just posted a long post about correcting all Hanna readers. You will be surprised how good they can read if used correctly. Sad thing is Hanna is not putting out correction notices. Look at my profile for the Hanna checkers thread I just created.

I’ll have a read of that, I did not know there are fixes that would make them better, maybe I can rescue my CA and MG kits.

Thanks,
