I've been having some trouble with my Sybon refractometer. I don't know if it's something I'm doing, or if something is wrong with the equipment. For example, the first time I took a salinity measurement today, it was 1.027 (my salinity was measured a couple days ago as 1.024, and there has been very little evaporation). I rinsed it in freshwater and dried it with the supplied cloth. I took it again and it was 1.024. I rinsed and took it again, and it was 1.025. This was all within 5 minutes. I put a little fresh water on the refractometer lastly, and it measured at 1.000, as it should.
I know refractometers are high-quality, accurate pieces of equipment. What in the world am I doing wrong, and how do I know what is the real salinity? The refractometer is new, only as old as the tank (about 3 weeks now), and has not been dropped or anything like that. I try to take the water sample from the same depth, and I try to tap all the bubbles out under the refractometer lens thingy each time. Do you have to add a specific amount of drops of water or something?
If anyone can help, I'd appreciate it!
I thought salinity would be the easy thing to measure amongst all these color changing tests, but it's proving to be the most hard to gauge thing.
