Measuring Salinity

With such a resounding response, I had to do my own inquiry. As all of you know hydrometers and refractometers do a good job with salinity/SG in the higher ranges, but not in the lower ranges. I mean, how would you distinguish between 1 And 2 ppt?
It seems to me that TDS monitors are the answer. There are a number of inexprnive ones hat will measure dissolved solids between 0 and 4999 ppm (4.999 ppt)
Certainly not useful for higher salinities, but much more precise in the lower range.

Hey, I have a question if you still get updates on this old thread... Well, 2 questions.
1: how would I go about finding the appropriate level of TDS for a given salinity?
2: how would I adjust for solids, such as calcium or trace metals, other than nacl that may be dissolved in the water? I have a TDS meter that measures via conductivity, but I'm not sure what & how different things might affect the reading.
I'm glad you posted this, because I've been struggling with how to measure for an F8 Puffer tank I've set up. Was looking at refractometers but was unsure if one calibrated on only one point (which I think is usually at high salinity) would work for an sg of around 1.008.

I used to use Hach Conductivity/ Salinity meter for judging salinity of 3ppt when treating for ick.
They worked well at low range, don't know todays prices, but I would imagine there are affordable ones, but then again, you always get what you pay for.
For example, buy a cheap heater, get cooked fish. Some things are important enough to spend a few extra bucks for.

I could of swore I used a refractor back in the day for my F8. Here's an accurate meter though.

That looks like a nice unit, especially with the auto calibration.I could of swore I used a refractor back in the day for my F8. Here's an accurate meter though.
