Im losing my mind.

I camt for the life of me know what my salinity is. I bought hanna, Milwaukee, a BRS refractometer. And none of them are getting me a results i feel im fine with. Got hanna yesterday opened the sachets calibrated it 35.1 all good. Rinsed it put it in my tank.. 1.024 77F. All good right? Got my brs refractometer calibrated it with the solution. Tool sample from my tank 1.026.
I tested my mixing station with hanna. It shows 1.024. My refractometer 1.027.

Any idea folks?

I suggest picking one and staying with it. They are all hobby grade testers and will have inaccuracies. Stability is more important than precision, in my opinion.

Your tank and your mixing station water all tested 1.024 with the hanna. The other refractometer seemed to give differing results. I'd probably go by what the Hanna was saying.

Saying that, you also mentioned you got the milwaukee too, but didn't mention any of the results with it.... So what did that one say?

if you buy a few more salinity checkers you will probably get a few more different readings. I have 3 different salinity devices and all 3 give a different reading. Just pick your poison and stick with it, stability is most important.

I like the vee gee refractometer. Supposed to be lab grade but honestly just love it for it’s ease of use and the fact it doesn’t drift easy. I buy calibration solution but there are home made recipes for It I believe too.

I went through the same thing at one point in time. I have a ln old optical refractometer, the Milwaukee digital refractometer, the Hanna conductivity pen, and the probe on my apex.
The thing that helped me out was making my own calibration/validation liquid. I don’t trust store bought calibration fluids.
Randy Holmes Farley had a article about making your own solution and it is just table salt and rodi water so it cost essentially nothing to make.
