New to the hobby with many questions

[reefer newby]

I just bought a rhs10atc refractometer. I have been reading about these on the internet. Seems there are aquarium saltwater refractometers and there are seawater refaractometers. Is there really a difference? If so , can someone explain? And does it really matter as long as my water tests at about 35ppt?

I just purchsed a RHS10ATC refractometer. I have been reading about these on the internet. Seems there are saltwater refractometers and seawater refractometers. Is there really a difference? With this one I bought , after careful calibration , my water tested @ 35 ppt. Is this about right?

I just saw the Milwaukee digital Refractometer. Should I go for that one or is my cheaper one good enough?

No, you bought the right one, no worries.

Does anyone use digital aquarium heater controllers? If so , which one would you recommend?
