Technical Authority and Trustworthy
• Meet international / national standard, adopt national standard Kjeldahl method: digest sample in concentrated sulphuric acid environment 、steam distillation in alkaline environment、boric acid absorption、indicator titration end-point color determinate method;
• Sonnen is one of the drafters of China’s national standard GB/T22923-2008;
• Sonnen is one of the drafters of the China's official standard JJF 109-2012《Calibration Specification for Nitrogen Analyzer》;
Product Introduction
• This Kjeldahl analyzer is designed by a professional team with years of R&D experience of high-level Kjeldahl analyzer, and is with the advantages of science, simplicity, high stability and super-high cost performance.
• Distillation of the sample can be finished by two buttons, which makes the analyzer is easy for operation.
Product Function:
• The amount of alkaline liquor is controlled by button and added quantitatively.
• Distillation is controlled by button.
• Steam flow, liquid level of the steam generator, and the circulating cooling water are all controlled automatically.
• Reagent adding to the sample and distillation could be handled by two buttons.
• Water saving design: It is guaranteed that the circulating water flow-limiting valve open only during the distillation, water-saving and free from worry. automatically control circulating water flow，free from manual operation.
• The panel is with the material of ABS engineering plastic, which is waterproof, electricity-proof and corrosion-proof.
