Q for those who use Aquarium Pharmaceuticals Kit

What is the scale of its nitrate test and its pH test? It says on the description below that it comes with a "freshwater pH" and a "high range pH". Also they sell a "Mini pH Kit - tests pH level from 6.0 to 7.6 - 250 tests per kit"

I am asking since my test kit (tetra) has pH in increments of .5 and does not have a nitrate test kit. Also the reason that I'm asking for the scale of its nitrate test is that I have found this:

w/c detects nirtrate from 2.5 to 100 ppm but costs $9

If anyone else can suggest a better test kit pls do so.

Thanks for the responses.

Looks like the Aquapharm test is what I need to get.

Seems like I need to get a separate nitrate test since I'm looking for one with a more detailed scale from 10-30.

Any info about the scale of Red Sea nitrate test kit would be apprciated.
