like digital calipers, I like a guestimate if its in that ballpark. more batteries to buy.

Works well for me and I read many reviews before purchase. I rinse it in RO/DI after each use.Does it work really well? It's much cheaper than the one posted by the OP.

It's what I use to measure salinity. If Rev wants to delete it he is welcome to do so.For the sake of accuracy in Rev's poll, do you vote yes because it is a digital device or no, because this isn't a refractometer?

You are correct. My immediate "knee jerk response" to Rev's question was measuring salinity. I didn't stop to think of the specific technology. Thanks for clarifying.I'm not criticizing, I'm just asking. I know others have confused conductivity meters and digital refractometers in other discussions.
My Analog Refractometer works just fine for a fraction of the cost and it does not need constant calibration like the digital models. Also using a $2 bottle of Distilled water or good RoDI water works as an endless source of zero value reference fluid and calibration fluid.
In your opinion should someone who is using a non digital traditional refractometer ditch it and buy a conductivity meter? If its more accurate I will go that route. That's my first time hearing about them. Is it similar to a E.C meter for hydroponics?I cannot see any reason to use it.
IMO, It is marketed to reefers who have convinced themselves that refractometers are good, and so a digital one is easier and better.
Hanna claims it is only accurate to ±2 PSU; ±2 ppt
So in essence, it cannot distinguish 33 from 37 ppt.
Conductivity meters are far more accurate, even from Hanna: ±1 ppt for 0.0 to 40.0 ppt, for much less money.
