The Nitracheck instruments, which has been field approved for years, measures the color change of Merckoquant nitrate measuring sticks spectrophotometrically and displays the result as nitrate content. Due to the electronic measurement of the color change of the test strips, a significantly higher accuracy is achieved compared to the human eye. When used correctly, the result only deviates by approx. ± 10 % compared to the laboratory analysis.
