Hanna pH/conductivity/tds checker thoughts

[smcquary]

What's your opinion on the Hanna low-range-ph-conductivity-tds-combo-pen-hi98129? Any thoughts on other testers?

There are several affordable TDS readers on Amazon and Ebay that are fairly accurate, at least accurate enough for Reef-keeping applications. The Hanna pH checker standalone unit is only like $40-45 so I'd get it and one of the cheaper TDS meters like this one. That way you'd save a good amount of money and save some time and hassle, not to mention some frustration, if one of the meters goes out on the combo unit.

I am mostly looking to test pH and salinity as I have a tds meter. I will check out the Hanna pH tester.

Thanks

You cannot test marine salinity with it as it doesn't read conductivity high enough. Otherwise, it seems like a good meter for pH and RO/DI monitoring.

Thanks Randy. Are you familiar with similar tools that can be used for pH and marine salinity?

Both in one? I do not recall seeing one.

They can be separate. Just looking for a good way to check pH and salinity.

Thanks

You'll probably have good luck with a pH probe or checker like the Hanna standalone unit and there are digital refractomers that are supposed to give a pretty good salinity readout.

Good conductivity meters that measure salinity are usually in the $100+ range and in my experience they're a little finicky. If you don't mind me saying I'd buy a Milwaukee refractometer to measure salinity which you can get for less than $100.
