Measuring Salinity???
I am having alot of trouble getting accurate readings from my swing arm meters. I have two, one is a instant ocean one that i've had for years and I just got a red sea one to compare. one will read 1.025 and one 1.023. I was thinking about getting a refractometer. Is that the most accurate way to go? Or do I really need to spend $100 on an electronic meter? Looking at this one from Marine depot.
http://www.marinedepot.com/Marine_De...TEOPRF-vi.html
Also can these be calibrated with zero TDS ro/di or does it have to be distilled? Thanks.

I don't agree!It has to be RO/DI or Distilled to be sure it's TDS if membrains are good.

I'd bet that she prefer fish to strip clubs, at least the tanks keep us off the street at night...

Did you read the link that Fat Tony posted? The RO water works but it's like trying to calibrate your speedometer while parked... If you really care about accuracy, in addition to the consistency that a refractometer will bring, you need to buy the pinpoint calibration fluid and then calibrate your refractometer out to 35ppm
