Is this a normal reading for salinity throughout a day

Yes but NEVER trust the Neptune salinity probe. It over time will get supper off and stress you out. Mine sadly went off when i broke my refractometer and so I freaked out and changed the salinity to dangerous levels. Neptune salinity probes are notorious for being really off. And caused me to kill one of my shrimp.

The overall level you show there is lower than usually recommended for a reef tank (35), but would be ok for fish only.
That degree of variation over a day is pretty small. Specific gravity 1.0228 versus 1.00236.
The probe works well for me, but has limitations.
It measures conductivity, not specific gravity.
Calibration can be tricky.
It can be affected by microbubbles.
It can be affected by power cords, as from heaters, running next to its cable.
Agree completely with always checking against a properly calibrated refractometer, either handheld or electronic.
