Comments: Not provided, but calibrates at sg 1.026. Better to me than calibrating off of distilled. I store this in a ziplock after opening. Yes, I would recommend this product to my friends.

Comments: This fluid is a perfect measure of 35 PPT or 1.026 SG I used it to calibrate my marinedepot refractometer. Works well, better than using distilled water. Yes, I would recommend this product to my friends.

Comments: Simply put, it does what it's supposed to do. Although I agree with the other reviewer that they should label what the fluid is calibrated to, which is 35 ppt. That little bit of information isn't anywhere to be found on the label. Yes, I would recommend this product to my friends.

Glad I found this stuff. by GARY

Comments: I bought the Pinpoint Salinity Calibration Fluid to fine tune my refractometer. After reading repeatedly that using pure water is not the best way to calibrate a refractometer, I decided to try this product. As many others have found (I read the Reefcentral forums), my refractometer was 3 thousandths off. So instead of 1.025, I was keeping my specific gravity closer to 1.022. I had to do a little research to find out the salinity of the Pinpoint Salinity Calibration Fluid. I contacted American Marine Inc. and was told that it is 35ppt. It would have been nice if that information were on the bottle. Yes, I would recommend this product to my friends.

Comments: This product seem to work great. I used it to calibrate my refractometer and found that it was off a bit when I had calibrated it with RO water. This gives me some peace of mind that I am measuring relatively correctly. Yes, I would recommend this product to my friends.

Calibration Fluid by JOHN LIKES

Comments: I bought this product to confirm the calibration of my refractometer. Most refractometers have you calibrate with distilled water but this only lets you know that your refractometer is accurate at 0ppt/1.000 specific gravity. With this product you can now know with certainty that you saltwater ppt/specific gravity is correct. Yes, I would recommend this product to my friends.
