after a month it stopped working properly, the salinity was reading at 1.020 when it was 1.025, but read 35 ppt on calibration. I was able to determine this by sampling the same water with a different refracterometer from the LFS. You pay for what you get in this case. Worked good while it lasted and the numbers were easy to see.

Buy something else. Even with calibration fluid this thing is still inconsistent with its readings. Though I did receive a hard shell case which was nice and fit the unit properly. Returning this one.

Accurate and easy to use - but the scale is so tiny you need excellent vision and daylight to read it. If you have not-perfect eyesight, this will not work for you.

Works well. Was perfectly calibrated when I received it, but planning on checking the calibration from time to time to see if it ever gets out of wack. I ordered 5 of these and 4 came in hard cases while 1 came in a soft case. I'm not totally sure why, but it seems to be a toss up whether you will get a hard or soft case? That's why I knocked off a star. I've used them for saltwater tanks measuring between 1.020-27 approximately with accuracy. I'd say it's a good price for what you get as well.

When I'm testing my aquarium water, I want immediate, clear results. I don't want to deal with temperature correction or ... I actually just stopped paying attention to what I was writing when I mentioned temperature correction.Just give me one simple, accurate reading to go by, and I'm happy. This tool does that. It's fast, it's tidy, and it's accurate. Yes, it's three times more expensive than a standard swing-arm hydrometer, but it's still very reasonably priced, and the savings in time and hassle more than compensate for the extra expense.

This works great and the price is wonderful. For my vision, with or without reading glasses, I have to unscrew the eye piece to the end of its threads. This makes it possible for the eye piece to just pull out of the housing. Also, you have to turn the eye piece all the way in for the instrument to fit in the case, so I am constantly running the eye piece to both extremes. Lens and printed scale is crystal clear, but the magnification seems just barely adequate, in that it leaves me squinting to differentiate between integers (i.e. the difference between 3 and 4 percent). Younger eyes may have not find this problem, it may be my vision.

Ordered this to check the salinity of a jellyfish tank I received as a gift. The plastic swing-arm hydrometer that came with it was not very accurate. After some research, I found that refractometers were the way to go, and while they are a little more expensive up front, they are well worth it.This one was one of the more affordable ones on Amazon. The actual unit is pretty well made and feels durable and sturdy in the hands. The accessories (pipette, carrying case) are nothing special, but adequate enough to use. Instructions were easy to follow, although there were a few grammar and spelling errors. Focus is easy and stays put. Gradient is clear and easy to read.Make sure you calibrate using distilled or reverse osmosis water. Point at a light source to clearly see the measurements.

My unit was off on slope calibration, so when following the directions to calibrate at 0% with RO/DI water, I was off by .005 when I measured a solution in the 1.026 range. As this was for a salt water tank, a difference of .005 salinity is a pretty big deal.After doing research, this is a very common problem with inexpensive refractometers. So make sure you calibrate to a solution much closer to the range you want to measure, rather than with RO/DI water, as the instructions suggest. The slope calibration on these units just isn't good enough.
