A test of Nitrate Test Kits

[Billybeau1]

0.25 to be exact. 0.25 x 4.43 = 1.1075

Either way, if your NO₃ is at 1 or below, you are probably in good shape.

 

[Boomer]

Well, if you want to get picky or be exact

0.25 x 4.4266438 = 1.1066609

 

[Billybeau1]

I should have known better.

Carry on my friend. :wavehand:

Oh geez, now everyone is going to start rumors about us. :lmao:

For low readings you may want to stick with the Sailfert, as it is NO3. The LaMotte is N-NO3 and only goes down to 0.2 N-NO3 x 4.4 = 0.88 ppm. Or this kit made for seawater

Ultra Low Nitrate Analysis

0.5 µM - 10µM Nitrate = 0.007 ppm - 0.14 ppm N-NO3 ( x 4.4) = 0.03 ppm - NO3- 0.62

Thanks for the tip. Have you tested the kit in your link? I am looking for a kit that is easier to read than the salifert. Maybe I will try the one in your link.

 

[Boomer]

No I have not. I just found it last week, when looking for other Nitrate kits out there.

emoore, even though the LaMotte tests nitrate-nitrogen, it still does a good job at low levels and is very easy to read. Probably the easiest I've seen yet.

Sorry to resurrect an old thread, but here's an idea

We'd all love to have a Hanna Nitrate checker. And maybe we can. Here's how:

First, use the Hanna Nitrite Low Range checker to determine the amount (if any) Nitrite in the marine sample water.

Then, what if we use the Hach NI-14 (Hach NitraVer 6 2076199) reagent (diazotization cadmium reduction) to reduce the Nitrate in our marine water to nitrite? Then we use the Hanna Nitrate Low range Checker to determine the Nitrite. If we subtract the Nitrate found in the first test, we should know the amount of Nitrate in the sample.

Boomer, what do you think?

So which company makes an electronic Nitrate test kit for SW?

 

[sghera64]

at hobby prices

So which company makes an electronic Nitrate test kit for SW?

And does so for hobbyist prices. . . like less than $60. :facepalm:

I know Hach makes a couple of electronic colorimiters for marine nitrate, but I'm not shulling out $400 for them.

I haven't seen a cheaper meter that will do the job.
