Hi I have had the same issue with three different lots. For me they are reading 0.0.My latest few boxes of HI782 (Nitrate High Range) reagents appear to have a bunch of duds in them. Like nearly half the packets will register like 0.5-1.0 ppm NO3. Usually when that happens, I retest with another packet and I get my normal 13-15 ppm. Anybody else experiencing this?
