Densitometer in RH Designs Analyzer

[Marcial]

I recently bought a RH Designs Analyzer Pro.
Just curious, how reliable is the built in densitometer function?
Thanks

I got the zone master II and would interest to know as well.

But is this densitometer is not actually absolute number but just relative?

it's pretty good but all relative to b+f.
