How come my tds is reading 995 ppm? (X10)

[Noah707]

I tested some freshly mixed saltwater and it's reading around 995ppm. I test rodi water and it says 0 so I'm pretty sure it's calibrated.. Are these supposed to be freshwater only? Couldn't find anything on it, it's the Hm digital tds-4.

A TDS meter on saltwater is meaningless. Of course you will have "dissolved solids" in saltwater. I'm not sure why you would even test this???

Saltwater has lots of total disolved solids. Only measure fresh.

I was just curious, thanks.
