Excellent choice June 24, 2010

I'm using this unit to measure the salinity in my fish tank and for the first time I really know the real value of this important parameter. At first I was using a regular plastic hydrometer and was trusting the results I was getting, but then I bought a second hydrometer and the readings were totally different from the first one. That's when I realized that I needed more precision, and this unit is of course more expensive, but the accuracy you get is worth the extra money. It turned out that the salinity in my tank was way too high and was the reason for several problems I was having with the aquarium. The unit it's extremely easy to calibrate , all you need is destilled water and 10 seconds of your time, and is also very easy to use.

It showed up out of the box calibrated and hasn't needed any adjustment. The entire unit seems solidly built, and is very easy to use.
