The most damaging line in a release sheet is the one left silently blank. If you did not test pH this batch, write not tested. If the ammonia reading came from one point rather than three, write one point. A record that hides its gaps will be trusted more than it deserves.
Small units can run this with a printed checklist and an outside laboratory a few times a season. Larger plants need a named release role, batch trends, and a written rule for a batch that fails one check but passes the rest.
