Review on Hanna Instruments Nitrate Checker HI782 by David Lesperance

It's fantastic and easy to use. Still, I gave 3 stars for the 7 minute timer. You have to wait 7 minutes, after that you will get a result message that the device will turn off automatically after 10 minutes. The problem is that I missed the check after 7 minutes and after 10 minutes the device turned off. So I've wasted about 3 reagents so far. Simple solution: remove the 7 minute timer or at least add a beep when the test result is ready in 7 minutes. Hope they fix this soon. Now I use a timer on my phone that notifies me in 7 minutes and I start reading. All the best.
