半自动凯氏定氮仪
Model：KDN
Introduction
The instrument is composed of digestion furnace (different types for selecting) and azotometer distillatory. The digestion furnace (numeric display model) is controlled by temperature control meter. It adopts infrared radiation heating. Insert the sample into the heating furnace to get the best heating effect. Through the drainpipe and the air-bleed three-way, poisonous gases (e.g. SO2) emitted from the digestion tube could be taken to the cloaca by water (the gases could also be recycled by vacuum pump and recycle bottle) which could control the emitting of poisonous gases and save the installation of ventilated case. Samples could be digested thoroughly in about 40-90 minutes (according to the amount of nitrogen).
