Semi-Automatic Kjeldahl Nitrogen Analyzer KDN

Measure principle steps of the instrument are shown as follows (Kjeldahl nitrogen determination principle)
sampling digestion distillation titration calculation
The digestion furnace (numeric display model) is controlled by temperature controlmeter. lt adopts infrared radiation heating. Insert the sample into the heatingfurnace 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 gasescould also be recycled by vacuum pump and recycle bottle) which could control theemitting of poisonous gases and save the installation of ventilated case. Samplescould be digested thoroughly in about 40-90 minutes (according to the amount ofnitrogen)
