Review on Hanna Instruments Nitrate Checker HI782 by Doug Hook

Like all of their products, this one is great. This is much better than the low range with fewer steps and is accurate. The only problem is that it's gathering dust right now because you can't find the reagents. They still sell testers with 10 reagents, but once they run out you're done until they release more. As with other reviews, always say 6 weeks.
