Using Nitrate HR reagents on the Nitrate LR checker?

[shadow1013]

I wasn't really paying attention that the HR was the newest one even though the LR was only a few month older. I hate the filter process of the LR and wondered if anyone has both and had tested the HR reagents in the LR checker to see if they read the same. I understand if you are above 9.99 then it won't read but if you are under would it work?
