PH tester and PH question

Are ph testers/ph up and ph down the same for saltwater as they are for freshwater?
Can I use a freswater ph tester in a saltwater tank?
And will the ph up / down work as well for saltwater?

Most tests are for either/or...SOME can be used for both SW or FWA but they will specifically say it on the package....You can not use PH up/down for freshwater in SW...You need to buy PH buffer for SW specifically.
