Purpose and Overview

NKP-1 type automatic nitrogen, phosphorus and potassium concentration analyzer is an intelligent analytical instrument that is controlled by a single chip computer and has built-in software to automatically process data, display intercept, slope, correlation coefficient, concentration, and print out the sample concentration.

NKP-1 automatic nitrogen, phosphorus and potassium concentration analyzer is suitable for using in soil, fertilizer, plants, environmentally friendly biochemical food and various scientific research units, colleges and universities.

NKP-1 automatic nitrogen, phosphorus and potassium concentration analyzer is based on the principle of photoelectric colorimetry to analyze the concentration of more than a dozen trace elements such as nitrogen, phosphorus and potassium. Colorimetric analysis, showing the concentration of the element in the display liquid.
