AUTOUTLET 8541957195 First Impressions

These seem spot on.

Not sure how accurate it is, but it's a good reference point. Ambient room light at night is not enough and makes what you're viewing dark. If you read the directions in the box for the refractometer it's for freshwater. And it is much more accurate than my old salinity meter. Waterproof if you accidentally drop it in the pool. My corals will be much happier now. It is a little cheaper made but it works great for the cost!

AUTOUTLET 8541957195 Final Thoughts

2 failed, 3 did not.

Just rinse with warm water afterwards. I bought this and a hydrometer because of the reviews saying its not accurate. Now that it's calibrated I love it! I HIGHLY recommend this to Aquarists! I have purchased before will buy again! I got this to have a more accurate read than the hydrometer. Too that makes it appear too cheap.
