Working well for over 3 years. By SoLiD on 11/14/11SoLiD would recommend this product to a friendIt takes some getting used to, but you have to convert the reading to Specific Gravity using a chart. I've left mine on for over 5 days with it constantly reading by accident without any negative results. If you have stray voltage from a pump, heater, or power head your readings will bounce all over the place, so be sure you don't have those issues first. It does what it says and it's pretty easy to remember that 53.0ms = 35ppm = 1.0259.
accuracy and a time saver! By David on 5/19/10David would recommend this product to a friendconsidering how many times, i check salinity/SG, i could have saved hours of time by using this monitor earlier.
i first tested it with two different calibration fluid samples and the unit was consistent with both.
it is very easy and quick to use. simply insert into water, swirl a bit, and wait up to 1 min for temp equalization. then read the number.
my only regret is not getting one sooner.
