KDN-BZ nitrogen determination distiller has following features: it adopts electrical heated tubes to produce steam from distilled water. Water level in steam generator is controlled by level controller. Each time a sample is distilled, the distilled water in the steam generator is supplemented automatically. It distils the digested samples and converts the ammonium sulfate generated during digesting into ammonia, which reacts with boric acid and generates ammonium borate. After titration, the content of crude protein can be calculated.
