Most swing arm hydrometer are not temperature compensating, so you have to measure the S.G. at a specific manufacturer recommended temp for it to have some accuracy.
That said, personally I have had very bad experiences with swing arm hydometers, so I would advise you to invest in something that is more trusting.

I believe this is a profound question and deserves a response.
There's nothing I know of that's immediate. If you have trouble keeping Starfish, Urchins, or snails more than just a few years then it could very well be salinity. Unfortunately it's really difficult to track because of how slowly a reduced salinity causes damage.
I often hear hobbiest discuss what a pain it is to have to turn over their Astrea and Turbin Snails after they fall on the sand bed. To me this is an obvious problem of low Salinity. Snails do not just fall off the glass.

I agree.
This is definitely a sign of water parameter problems and more often salinity.
