No, not exactly. You could simply print your pyro stained test negatives directly with your UV process and evaluate the results visually, which is the end result anyway.

But if you expect to practice sensitometry with UV processes without a UV reading densitometer, then yes, the results, though not exactly a hit and miss proposition, will lack the accuracy we expect from BTZS testing.
