These pocket meters directly measure nitrate ion and nirate-nitrogen concentrations in 0,3 ml sample (or 0,05 ml sample with sampling sheet B). The unique flat sensor allows measurement of viscous liquids, solids, and even powder samples. The sensor does not need to be dipped into the sample, a few drops are sufficient.
