Bad test kit?

[Goaway]

Went to LFS bought a seachem nitrite/nitrate test kit. I am pretty sure it's bad. There is no expiration date on the box.
I wanted to get an accurate reading on my nitrates.

So, anyhow. A = tap water . B = Tank water, R = reference test that came with the kit. Its supposed to read at 10mg/l

Yeah those are known to be very inaccurate. Try salifert nitrate testing kit.
