Fantastic tester for saltwater tanks! The HI782 makes nitrate testing so much easier and more accurate. No more struggling with color charts or second-guessing results. The digital reading is clear and reliable. It is perfect for keeping my reef tank in check. Highly recommend for anyone wanting stress-free nitrate testing.

Of all the Hanna Checkers, this is the only one I have worries about the accuracy. But probably works ok for coarse readings that a beginner would want, and is easier to use than the Low Range option.If you are like me, a new reefer, and don't want to read the color change on the standard kits, this will work. While the tolerance is pretty big, I am aiming for a 1-5ppm Nitrate in my tank, and I trust this to tell me I am at 0ppm, between 1-5ppm, or above 5ppm. So it will do the job, but I will probably move to another option as I become better at reefing and start aiming to keep my Nitrate closer to 1ppm.I tested 4 things first day I got it; My aquarium 3 times, and fresh made saltwater 1 time.My Aquarium was 3.8ppm, 4.9ppm, and 4.6 ppm. So the accuracy is probably better than the +/-2ppm claimed.Fresh saltwater was 0.0 ppm. Did not error out, gave a clean 0.0.1 week later, I tested my aquarium again, only once, and got 3.9ppm. To be fair, I only have 3 small fishes in there right now, so there is not a huge bio load right now. Once I have more critters in there, this should start to detect the weekly increase, if not, at least monthly it will let me know if I am trending up or mostly stable.Also, this says to mix the reagent for 2min, then take measurement 7 min later. I tested this as well, after 2 min of mixing, I started a timer and checked the reading every minute for 10 minutes.I got 1min:2.4, 2min:2.7, 3min:3.1, 4min:3.3, 5min:3.5, 6min:3.6, 7min:3.9, 8min:3.7, 9min:3.9, 10min:3.9So it seems stable after the 7 minutes, so error is probably more to do with the reader itself, and if you spilled some reagent.Final Analysis: Good for beginner, probably want something more accurate long term. But this Checker is more accurate than the standard kits I would say, because it removes the human reading color element of the test. Using one of the standard color matching tests, I thought I was reading 10ppm, which seemed much higher than my 3 little fishes would make. This Checker seems to confirm that, and I trust it more than that other test.

This is such a good tool to measure nutrients in you tank. This checker comes with a small amount of reagents to be able to do the measurements but you will have to buy more packs later.

Certainly one of the easier checkers to use. Seems pretty accurate and consistent. Worth the purchase.

item works great!
