The K9860 automatic Kjeldahl nitrogen analyzer is an automatic distillation and titration nitrogen measurement system designed based on the classic Kjeldahl nitrogen determination method. The brand-new K9860 has a dominant core control system, a highly automated whole machine and parts, resulting in the excellent quality of the K9860. High-precision corrosion-resistant liquid filling pump and linear motor micro-control titration system ensure the accuracy of experimental results. It is widely used in food processing, feed production, tobacco, animal husbandry, soil fertilizer, environmental monitoring, medicine, agriculture, scientific research, teaching, quality supervision and other fields to determine nitrogen or protein content.
