土壤氮分析仪
Reference total nitrogen for fertility trials and carbon-nitrogen studies calls for a proven method. Choose Kjeldahl digestion at 350–420 °C with automatic potentiometric titration, or combustion for faster runs. The system covers 0.01–10% N on 0.1–5 g samples, with 6–20 positions and repeatability of RSD 1.5% or better. Specify Kjeldahl or combustion in your inquiry.
