Today completed my second stage of fermentation of wine. I checked the
hydrometer reading and it was 1.000.

Out of interest, I also checked the specific gravity of the wine with a
clinical refractometer and it read 1.033. Thinking that my refractometer
needed adjusting, I checked a distilled water reading which as it should be
was 1.000.

Why the difference in readings for a clinical refractometer and hydrometer?

check your hydrometer with water also as it sounds like it's possible that
the paper tube was knocked loose and your readings are off

Could also be calibrated for a different temperature

Refractomters are useless once fermentaion has begun. Only use them when
testing grapes in the field. when you're about to purchase them or just after
crushing.
