First post over here.
I have been doing some extensive theoretical research on which water testers (electronic/digital) from TDS, Hanna, Extech, etc., could help me out to monitor the basics on salt water pools.
Still don't find which are the different "things" that have to be tested on a normal fresh water pool and a salt water pool.
Also I have read in some places that basically one should test pH, ORP, Minereal/Salinity and Temperature.
But in other places they say it should be: pH, Chlorine, Alkalinity, Calcium Hardness and Temperature.
How to know which to monitor? I leave on the beach (Los Cabos) and most of the pools over here are Salt Water systems.
It wouldn't worth to buy testers, let's say the TDS COM-100 + the TDS ORP-200 to monitor and take care of some salt water pools if they don't measure what I need right?
Also I was looking for the Hanna HI93745 which tests CHLORINE, HARDNESS, IRON & pH METER and it is also more expensive as well as the HI 98204 Water Test from Hanna Also (pH/ORP/EC/Temperature in One Unit)

I am not a professional on this. I am starting with this and I am thinking on investing maybe a max. of $200 USD for this. Just need to check that the pools are ok. Also found other testers around $900 or $2,000!
These pools are not used heavily. Are from houses.
If my question has to go in another thread I will gladly move it to where it belongs. Any help will be much appreciated!
