I did a Google search and I was able to find a link to the exact refractometer that I purchased a little over a year ago and am quite happy with. I was originally shipped their newest version of this refractometer and called them to specify that this Reef Sea version is the exact one I wanted. I was pleased to reach a real human being on the phone who swapped out my refractometer no questions asked and covered the shipping for the mix up. If you intend to purchase this refractometer you may want to call them directly to make sure this is what they send.

Thanks for that. From that link, it looks like this is the scale you see through your refractometer?

I can't tell for sure from this image on the website, but it looks like 35 ppt aligns with SG 1.025. If so then I'm not sure it is a true seawater refractometer. If I understand correctly, in seawater 35 ppt should align with 1.0264. Hopefully that is what you see when you look through yours.

There may be a typo or a picture discrepancy in the advertisement from nisupply, but this is how my refractometer shows my tank water right now. I check the calibration of it regularly to my fresh salt batch mixed to 1.0264 at 77°f/25°c using a TM float. I have only had to adjust the refractometer 1 time in a little over a year's time that I have owned it. It consistently agrees with my TM float and that's all that matters to me.

The funny thing to me is that I usually watch PPT so I don't even look at the SG scale unless I am calibrating the tool to my TM float. Because of that I didn't even notice that the picture on the website was incorrect...LOL.

Pictures are losing all meaning in the AI age. I recently bought a conductivity meter on eBay. I’m very happy with it, but it was only later that looking closely at the picture, the words on the face of it were gibberish and not actual words. lol
