I do calibrate it each time I use with a home-made calibration fluid. It works a treat, super cheap, and easy to read. Every saltwater keeper should get one as a back-up salinity device.

    5.0 out of 5 stars Does the job, exactly what lots of LFS uses.

    This little refractometer works great, it is simple and comes with multiple pipettes, a nice case, a microfiber cloth, and the calibration screwdriver. I would definitely get some distilled water and calibrate it before use, I think mine was off by a little bit when it arrived. Definitely skip the super expensive ones, this will last you for a long time if taken care of. It also can be focused in the handle. The pictures in the listing are accurate.

    5.0 out of 5 stars It is really good I will be getting more

    It's a really good price and works really good so I do recommend it is perfect

    5.0 out of 5 stars Accurate and worth the money

    c. · March 1, 2022

    This refractometer works great - it's accurate and extremely easy to use and maintain. The only trick is you need to calibrate it before using it on your fish tank, etc. Calibration is super easy - get a gallon of spring water from the store (mine was a whopping $0.99), and use a few drops of that to ensure that the device is calibrate - it should be reading 0 and 0% on each side, respectively. Once that is done, you can use it to accurately test whatever needs testing. I have compared it with my other salinity gauges for my saltwater aquarium, and this refractometer is consistently accurate while my other gauges are not. I also appreciate that this refractometer comes with a cleaning cloth, three pipettes for water drop collection and application, clear instructions, and a protective case. All in all, this was totally worth the money - I highly recommend this product.

    4.0 out of 5 stars Wrong range for pools

    A.E. · June 19, 2023

    Nice gadget for the money. But, if you are buying this to monitor your pool, be advised you will be reaching the upper limit for salt concentration at just the fifth bar from the bottom of the scale. That is 1.005 specific gravity or 6.8 parts per thousand which is 6800 parts per million. Around 4500 PPM is the reccommended ceiling for saltwater pools. It works, but all your action will be in the bottom 5% of the scale.Do remove the little rubber cap and calibrate zero using distilled water and a small flat blade screwdriver.I went ahead and bought a digital combo meter that measures salinity, PH, temp, and TDS. That should save some time over this if it works as advertised. It was more than twice the money but hey, it's all in the name of science. I might even come back and let you know how it worked out.

    Works well and is consistent. I can see rust already forming in the hinge after only five months but doesn't appear to be effecting function.
