Usage overview 

    KDN The series of nitrogen fixing instruments work with Kjeldahl nitrogen fixing principle, which absorbs the advantages of similar products at home and abroad and is carefully designed by the company's scientific researchers. The instrument has stable performance and easy operation. The products are divided into two series: fully automatic and semi-automatic. There are two types of heating methods. One is to use the commonly used electric heating pipe heating method abroad. Its advantage is that it can be applied to different water sources. Another type of heating method adopts electrode type heating method, which can be applied to water sources with relatively low conductivity, but it has the advantages of rapid heating and no need to set up a water level control device.
