nchkThe Nitrachek instrument is field approved since many years for the measurement of Nitrate in Soils, Substrates, Soil solutions and press-sap of plants. The instrument reads the color change of Merckoquant Nitrate test-sticks electronically, and thus very accurately. Results of Nitrate tests with Nitrachek vary only by ± 10 % compared to an analysis with a Ion-meter (i.e. Laboratory standard), if the instrument is used professionally.
